Subject: [PATCH v4 3/4] Input: adp5589: unify ret & error variables
Date: Thu, 5 Mar 2020 15:14:04 +0200	[thread overview]
Message-ID: <20200305131405.6598-3-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20200305131405.6598-1-alexandru.ardelean@analog.com>

Both variables are used mostly in the same way in the probe function.
Having both means that we need to copy 'ret' to 'error' before exiting, so
just use 'ret' everywhere.
