4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Benjamin Tissoires <benjamin.tissoires@redhat.com>
commit 4392bf333388cabdad5afe5b1500002d7b9c318e upstream.
hid_ignore_special_drivers works fine until hid_scan_report autodetects and
reassign devices (for hid-multitouch, hid-microsoft and hid-rmi).
Simplify the handling of the parameter: if it is there, use hid-generic, no
matter what, and if not, scan the device or rely on the hid_have_special_driver
table.
This was detected while trying to disable hid-multitouch on a Surface Pro cover
which prevented to use the keyboard.
