* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: appletouch - implement reset-resume logic Input: i8042 - retry failed CTR writes when resuming Input: i8042 - add Fujitsu-Siemens Amilo Pro V2030 to nomux table Input: pcspkr - remove negative dependency on snd-pcsp Manually fixed up trivial conflict in drivers/usb/core/quirks.c

/* List of quirky USB devices. Please keep this list ordered by:
|
|
* 1) Vendor ID
|
|
* 2) Product ID
|
|
* 3) Class ID
|
|
*
|
|
* as we want specific devices to be overridden first, and only after that, any
|
|
* class specific quirks.
|
|
*
|
|
* Right now the logic aborts if it finds a valid device in the table, we might
|
|
* want to change that in the future if it turns out that a whole class of
|
|
* devices is broken...
