HID: be more strict when ignoring out-of-range fields
I have a logitech USB keyboard with extra inet/media keys. In kde I have them configured to launch various utilities. With this commit, these keys will "stick", and instead of a single konsole window or krunner dialog or whatever, it continues launching konsoles or toggling the krunner dialog on and off. Switching to a text VT and killing X gets me the system back, but of course without X, and launching X/KDE over again results in unresponsive hotkeys.
Apparently, one of these "out of range" fields translates to a key-release for at least some of the extra keys, without which they stay pressed and auto-repeat.
gentoo/amd64 system, logitech wireless usb keyboard, kde 4.7.97 (aka 4.8-rc2), xf86-evdev-2.6.0, xorg-server-1.11.3.
I can attach .config later (headed to work now).

I just confirmed that reversing that commit against 3.3.0-rc1-167-gf8275f9 eliminates the issue, so it is definitely that commit triggering it.
Meanwhile, here's my current kernel config as promised.
The problem remains as of 3.3.0-rc2-172-g23783f8. Reverting still eliminates it.
Bug seems to have been overlooked in the 3.2 -> 3.3 regression list. Adding the block on the tracker bug and changing the summary to reflect the regression will fix that, I hope.
AFAIK the bug is still here on rc5. I've applied the regression patch locally tho, so have to manually verify it with a reset to upstream, build and boot to X/KDE, from time to time. Last I did, it was still unfixed.
