HID: adjust report descriptor fixup for MS 1028 receiver
commit 0fb21de0799a985d2da3da14ae5625d724256638 upstream
HID: adjust report descriptor fixup for MS 1028 receiver
[Backport to 2.6.27: cebbert@redhat.com]
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.
