Subject: drivers/media/IR/ir-keytable.c: fix binary search
X-Git-Tag: v2.6.37-rc1~16
X-Git-Url: http://bbs.cooldavid.org/git/?p=net-next-2.6.git;a=commitdiff_plain;h=0d07025effd3da8b9c74f18448823175f4c63a73

drivers/media/IR/ir-keytable.c: fix binary search

The input-large-scancode patches changed the binary search in
drivers/media/IR/ir-keytable.c to use unsigned integers, but
signed integers are actually necessary for the algorithm to work.
