HID: fixup the conflicting keyboard mappings quirk
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. Cc: <stable@vger.kernel.org> Fixes: 6ce901eb61 ("HID: input: fix confusion on conflicting mappings") Reported-by: Fredrik Hallenberg <megahallon@gmail.com> Reported-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
