2020-02-18HID: hid-bigbenff: fix race condition for scheduled work during removalHanno Zulla1-0/+6
It's possible that there is scheduled work left while the device is already being removed, which can cause a kernel crash. Adding a flag will avoid this. Signed-off-by: Hanno Zulla <kontakt@hanno.de> Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com>
2020-02-18HID: hid-bigbenff: call hid_hw_stop() in case of errorHanno Zulla1-5/+10
It's required to call hid_hw_stop() once hid_hw_start() was called previously, so error cases need to handle this. Also, hid_hw_close() is not necessary during removal. Signed-off-by: Hanno Zulla <kontakt@hanno.de> Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com>
2020-02-18HID: hid-bigbenff: fix general protection fault caused by double kfreeHanno Zulla1-2/+8
The struct *bigben was allocated via devm_kzalloc() and then used as a parameter in input_ff_create_memless(). This caused a double kfree during removal of the device, since both the managed resource API and ml_ff_destroy() in drivers/input/ff-memless.c would call kfree() on it.
