HID: adjust report descriptor fixup for MS 1028 receiver
Report descriptor fixup for MS 1028 receiver changes also values for Keyboard and Consumer, which incorrectly trims the range, causing correct events being thrown away before passing to userspace. We need to keep the GenDesk usage fixup though, as it reports totally bogus values about axis. Reported-by: Lucas Gadani <lgadani@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
