USB: ch341: fix TIOCMIWAIT and disconnect

2013-03-25T20:50:52Z

Use tty-port modem-status-change wait queue on which processes are woken up at hangup and disconnect. Currently a process waiting on modem-status changes will not be woken on device disconnect as wake up was only done in dtr_rts which isn't guaranteed to be called (e.g. if HUPCL is not set). Also remove the redundant wake-up call from dtr_rts. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: ch341: replace custom ioctl operation with tiocmiwait

USB: ch341: fix use-after-free in TIOCMIWAIT

2013-03-21T22:59:03Z

Use the port wait queue and make sure to check the serial disconnected flag before accessing private port data after waking up. This is is needed as the private port data (including the wait queue itself) can be gone when waking up after a disconnect. Cc: stable Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: ch341: fix port-data memory leak

2012-10-25T16:36:57Z

Fix port-data memory leak by moving port data allocation to port_probe and actually implementing deallocation. Note that this driver has never even bothered to try to deallocate it's port data... Compile-only tested. Cc: Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: Serial: ch341.c: remove debug module parameter

2012-09-18T09:15:17Z

Now that all usb-serial modules are only using dev_dbg() the debug module parameter does not do anything at all, so remove it to reduce any confusion if someone were to try to use it. CC: Johan Hovold CC: Alan Stern CC: Rusty Russell CC: Mauro Carvalho Chehab Signed-off-by: Greg Kroah-Hartman

USB: serial: remove debug parameter from usb_serial_debug_data()

2012-09-18T08:58:57Z

We should use dev_dbg() for usb_serial_debug_data() like all of the rest of the usb-serial drivers use, so remove the debug parameter as it's not needed. Signed-off-by: Greg Kroah-Hartman

USB: serial: ch341.c: remove dbg() usage

2012-09-14T00:18:10Z

dbg() was a very old USB-serial-specific macro. This patch removes it from being used in the driver and uses dev_dbg() instead. CC: Johan Hovold CC: Alan Stern CC: Rusty Russell CC: Mauro Carvalho Chehab Signed-off-by: Greg Kroah-Hartman

USB: serial: ch341: make the reset_resume callback actually work.

2012-05-16T15:36:13Z

I hooked up the wrong callback in my previous patch, this should fix it. Reported-by: Alan Stern Cc: Johan Hovold Cc: Rusty Russell Cc: Mauro Carvalho Chehab Signed-off-by: Greg Kroah-Hartman

USB: serial: ch341: put reset_resume callback back.

2012-05-15T22:41:47Z

A few patches ago, I removed the reset_resume callback, changing it to resume instead. Now that the usb-serial core supports reset_resume, put this driver callback back as well, so it should work identically to how it was originally. Now if this function really is doing what it should be doing, well, that's a different story, but we are at least doing the identical thing that we were before...

USB: serial: rework usb_serial_register/deregister_drivers()

2012-05-08T22:46:14Z

This reworks the usb_serial_register_drivers() and usb_serial_deregister_drivers() to not need a pointer to a struct usb_driver anymore. The usb_driver structure is now created dynamically and registered and unregistered as needed. This saves lines of code in each usb-serial driver. All in-kernel users of these functions were also fixed up at this time. The pl2303 driver was tested that everything worked properly. Thanks for the idea to do this from Alan Stern.
