v1.12	Jan Dumon	Added missing Vendor/Product ID's	Use the port_spec received from the device to create the network device	instead of a fixed value. The HSO_INFO_CRC_BUG flag could be missed 	this way.v1.11	Jan Dumon	Changed the order of things when stopping the network interface.	This fixes the crash that still could happen by a hot removal of the device.v1.10	Jan Dumon	Set a bunch of pointers to NULL after they were freed.	This fixes a crash triggered by a hot removal of the device.v1.9	Denis Joseph Barrow	Fixed supports_autosuspend in the hso_driver structure 	to be only defined if the CONFIG_HSO_AUTOPM is defined.	Denis Joseph Barrow	Fixed 2 bugs found by Jeroen Elebaut	Compiling on 2.6.20 didn't work because my check	the NETDEV_HAVE_DEV define was out by 1 kernel release	i.e. the net_device structure didn't have the dev	member defined till 2.6.21 rather than 2.6.20	also print_hex_dump_bytes doesn't exist till 2.6.22	so I had to define a static of this function which does this	for CONFIG_HSO_DEBUG on kernels prior to 2.6.22	Denis Joseph Barrow	Added 1 liner patch submitted by Oliver Neukum	which fixed flag marking device was running	before URBs were submitted in hso_net_open	which might cause them to complete too early	& fail to resubmit.	Denis Joseph Barrow	Added names of option hso developers to hso.c	Denis Joseph Barrow	Fixed kernel oops when opening control port,	as code mistakenly thought it was a modem port 	& issued a tiocmget_submit_urb to it.	Denis Joseph Barrow	Fixed compile bug when CONFIG_HSO_DEBUG is defined.	Denis Joseph Barrow	Fixed code to compile on 2.6.11	Fixed incorrect usage of kref_put.	Denis Joseph Barrow	Fixed a bug in hso_connect.sh which had some	form of italic quotes in the AT+CGDCONT command	got from a previous bugfix.	Denis Joseph Barrow	Removed retry_unthrottle_workfunc code I accidently	left lying around.v1.8	Denis Joseph Barrow	Added safe_usb_unlink_urb & safe_usb_kill_urb	which check whether a urb is in flight before stopping it.	kernels prior to 2.6.24 will do a kernel oops if the	device is disconnected while networking is going on	if this check isn't done. linux kernels 2.6.24 on do the 	check if (!urb->ep) return; in usb_kill_urb & usb_submit_urb 	we cant do this because urb->ep doesn't exist prior to 2.6.24.        prior to 2.6.23 so we need the -EINPROGRESS check.	Denis Joseph Barrow 	Small mod to AT+CGDCONT call in hso_connect.sh	reported as a bug.	Denis Joseph Barrow	hso_suspend & hso_resume are used by software suspend	& suspend to disk as well as autosuspend	these functions are always defined in	include/linux/usb.h so I'm leaving them defined in all	cases for safety as there are several config options	whose names have been changed between kernel versions	which may use these function.	Denis Joseph Barrow	Added patch by Paulius Zeleckas to set rfkill type to WWAN.	Denis Joseph Barrow	Added some new device id's supported by the hso driver.	Denis Joseph Barrow	Added Johnathan McDowells from patch which prevents an oops crash 	in rfkill from netdev@vger.kernel.org.	Denis Joseph Barrow 	Moved serial_open_count in hso_serial_open to	prevent crashes owing to the serial structure being made NULL	when hso_serial_close is called even though hso_serial_open	returned -ENODEV also put in sanity check in hso_serial_close	to check for a valid serial structure which should prevent	the most reproducable crash in the driver when the hso device	is disconnected while in use.	Denis Joseph Barrow	Added Data Carrier Detect etc. to hso_tiocmget.	Took out /proc filesystem hso related stuff to force	connection manager developers to use /sys filesystem stuff.	Made function of common code which made ttyHSx /proc filesystem	entries for mux & bulk serial devices.v1.7    Denis Joseph Barrow	Added back old procfs entries so that legacy versions	of connection managers still work.	Denis Joseph Barrow	Added Joffry Bellavia's port.sh script.	which locates application,diagnostic & control ports	for the user.v1.6	Denis Joseph Barrow	Put MOD_INFO back to show if CONFIG_HSO_AUTOPM & CONFIG_HSO_DEBUG        is set or not removed warning about disabling CONFIG_HSO_AUTOPM if        the kernel version is too old, also fixed some sloppyness found	by Peter Henn.	Fixed compile bug which left reset_resume method	defined for kernels prior to 2.6.22 where it didn't exist.v1.5    Denis Joseph Barrow	Updated README	Applied Adrian Bunks hso_create_bulk_serial_device(): 	fix of a double free patch from the linux-usb mailing list.	Made usb_drivers reset_resume function point to	hso_resume this fixes problems when the network	interface is left idle for a few minutes.	Possibly reset_resume should initialise hardware        more but this works in the common case.        Added check for IFF_UP in hso_resume this should        eliminate -EINVAL (-22) errors caused from        urb's being submitted twice once by hso_resume        & once in hso_net_open if suspend/resume USB power saving	mode is enabled.        Added s setpwr.sh script so that USB power saving mode can        be switched on or off quickly in the driver without having        to walk through sysfs.        Removed usb_driver_claim_interface & usb_driver_release_interface        calls as they were deemed by Paulius Zaleckas on the        linux usb mailing list to be unneccessary.        Improved hso_connect.sh script to make it automatically        detect the application port.        Improved hso_connect.sh so that it automatically finds        the application port.	Removed usb_driver_claim_interface & usb_driver_release_interface	calls as they were deemed by Paulius Zaleckas on the	linux usb mailing list to be unneccessary.v1.5-rc1 Denis Joseph Barrow	Took updates upto 2.6.27-rc5,	A new structure hso_mutex_table had to be declared statically	& used as as hso_device mutex_lock(&serial->parent->mutex) etc	is freed in hso_serial_open & hso_serial_close by kref_put while	the mutex is still in use.	This is a substantial change but should make the driver much stabler.	Patch to stop loss of characters on the hso modems,	this patch throttles & unthrottles the modem by	not putting out urbs until the tty/line discipline layer	has enough space for newly received packets.	serial ports. This is required for firmware diagnostics	being done at Option.v2.6.27-rc3 Denis Joseph Barrow	Taking code directly from 2.6.27-rc3 will be using	the official linux kernel version as a basis for	our future releases & porting our bugfixes onto this.	Denis Joseph Barrow	Fixed a problem found by a firmware engineer, the	program basically in hso_std_serial_write_bulk_callback was being	not sanity checking serial->tty was not NULL before calling tty_wakeup	this resulted in a race condition where urbs  after    	serial->tty was shut down. maybe more needs to be done here.    	Moved kref_put in hso_serial_close as refcnt was incorrectly    	going to zero  when serial->open_count went to zero    	which was not consistent with hso_serial_open.	A similar patch was posted to the linux usb mailing list.	1.4     Denis Joseph Barrow        Fixed dev_kfree_skb happening too many times when hso_start_net_device        is called from hso_resume. This manifests itself as a crash after a        kernel message saying that the hso driver is transmitting lingering data            Renamed hso driver printk macros to have a prefix HSO_ this        was needed as the kernel also defines a macro called WARN in 2.6.27-rc1        which hso.h also defined.            Fixed a tty line stuff needed to compile for 2.6.27-rc1            Made calls to hso_mux_submit_intr_urb use GFP_ATOMIC in their        allocations like the 2.6.27-rc1 driver this prevents the kernel        trying to sleep while in interrupt.1.3	Peter Henn	- correct USB interface initialisation for ICON322	- correct some compile warnings1.2	Filip Aben	- Added frame length lower boundary checking	- Catch failed opens and unwanted closes.	- Set DTR/RTS at open()	- Add hso_tiocmset() locking	- Use usb_unlink_urb() when in_interrupt.	- Removed 'Suspend' modinfo and replace with more general 'Flags' which should contain all compiler defines.1.1	Filip Aben	- Added SIOCSETSUSPEND ioctl for serial ports: Enables or disables selective suspend if supported by kernel. 	- Added SIOCSETRADIO ioctl for serial ports:  Enabled or disables the radio.	- Icon401 support	- Added sysfs support	- Added GE40x, GTM382 devices	- Fixed APP2 port support	- Fixed crash when closing active port1.0	Filip Aben	- Fixed Interrupt endpoint bug for HS speed devices ( Icon321 )	- Major overhaul of devices structure and way of working.
