Subject: [PATCH] input: alps: remove redundant assignment to variable ret
Date: Wed, 3 Jun 2020 14:57:42 +0100 [thread overview]
Message-ID: <20200603135742.130852-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The variable ret is being initialized with a value that is
never read and it is being updated later with a new value. The
initialization is redundant and can be removed.
Addresses-Coverity: ("Unused value")
