3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiri Kosina <redacted>
commit 8e7b341037db1835ee6eea64663013cbfcf33575 upstream.
The ignore check that got added in 6ce901eb61 ("HID: input: fix confusion
on conflicting mappings") needs to properly check for VARIABLE reports
as well (ARRAY reports should be ignored), otherwise legitimate keyboards
might break.
Fixes: 6ce901eb61 ("HID: input: fix confusion on conflicting mappings")
