Subject: [PATCH] ath10k: remove redundant error check
Date: Tue, 28 Feb 2017 11:14:39 +0000	[thread overview]
Message-ID: <20170228111439.19546-1-colin.king@canonical.com> (raw)

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

The check on ret for an error is redundant because it is already been
checked for non-zero earlier on and ret is never non-zero at this point.
Fix this by removing the redundant check and error message.
