Subject: [PATCH] input: synaptics-rmi4: check for non zero version logically dead code
Date: Tue, 20 Dec 2016 09:56:49 +0000	[thread overview]
Message-ID: <20161220095649.7674-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

version is a u8, the check for version > 0 means that version can only
be zero, so the subsequent check for version != 0 is never true and
hence is redudant code and can be removed.
