Input: remove third argument of usb_maxpacket()

2022-04-23T08:33:53+00:00

The third argument of usb_maxpacket(): in_out has been deprecated because it could be derived from the second argument (e.g. using usb_pipeout(pipe)). N.B. function usb_maxpacket() was made variadic to accommodate the transition from the old prototype with three arguments to the new one with only two arguments (so that no renaming is needed). The variadic argument is to be removed once all users of usb_maxpacket() get migrated.

Input: cm109 - do not stomp on control URB

2020-12-11T21:17:36+00:00

We need to make sure we are not stomping on the control URB that was issued when opening the device when attempting to toggle buzzer. To do that we need to mark it as pending in cm109_open().

Input: cm109 - remove needless check before usb_free_coherent()

2020-07-07T18:01:37+00:00

usb_free_coherent() is safe with NULL addr and this check is not required. Signed-off-by: Xu Wang Link: https://lore.kernel.org/r/20200707030905.3123-1-vulab@iscas.ac.cn Signed-off-by: Dmitry Torokhov

Input: cm109 - validate number of endpoints before using them

2017-03-16T20:56:50+00:00

Make sure to check the number of endpoints to avoid dereferencing a NULL-pointer should a malicious device lack endpoints. Fixes: c04148f915e5 ("Input: add driver for USB VoIP phones with CM109...") Signed-off-by: Johan Hovold Cc: stable@vger.kernel.org # 2.6.28 Signed-off-by: Dmitry Torokhov

Input: cm109 - spin_lock in complete() cleanup

2016-05-04T23:01:42+00:00

Complete() will be run with interrupt enabled, so change to spin_lock_irqsave(). Signed-off-by: Ming Lei Signed-off-by: Dmitry Torokhov

Input: cm109 - fix handling of volume and mute buttons

2016-05-04T23:00:54+00:00

The CM109 driver reported key press events of volume up / down and record / playback mute buttons, but no release events. Report those events properly by handling volume and mute keys seperately. For the record and playback mute buttons, only presses are registered by the CM109, therefore simulate press-n-release. This fixes the volume control buttons of various USB headsets.

USB: input: cm109.c: fix up dev_* messages

2012-05-04T22:32:55+00:00

Previously I had made the struct device point to the input device, but after talking with Dmitry, he said that the USB device would make more sense for this driver to point to. So converted it to use that instead. CC: Dmitry Torokhov CC: Axel Lin Signed-off-by: Greg Kroah-Hartman

USB: input: cm109.c: fix up dev_err() usage

2012-05-02T00:56:38+00:00

We should always reference the input device for dev_err(), not the USB device. Fix up the places where I got this wrong. Reported-by: Dmitry Torokhov CC: Axel Lin Signed-off-by: Greg Kroah-Hartman
