Subject: [PATCH] drivers/misc: ti-st: remove redundant assignment to variable i
Date: Mon, 2 Dec 2019 15:13:52 +0000 [thread overview]
Message-ID: <20191202151352.55139-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The variable i is being initialized with a value that is never
read and it is being updated later with a new value in a for-loop.
The initialization is redundant and can be removed.
Addresses-Coverity: ("Unused value")
Signed-off-by: Colin Ian King <colin.king@canonical.com>
