Subject: [PATCH] Input: atmel_mxt_ts - Remove unnecessary byte_offset check
Date: Sun,  8 Oct 2017 19:44:18 +0100	[thread overview]
Message-ID: <1507488258-22409-1-git-send-email-chris.gekas@gmail.com> (raw)

Variable byte_offset is unsigned so checking whether it is greater or
equal to zero is redundant.
