Subject: [PATCH 6/8] mwifiex: check if mwifiex_sdio_probe_of() fails and return error
Date: Fri, 27 May 2016 10:18:20 -0400	[thread overview]
Message-ID: <1464358702-19083-7-git-send-email-javier@osg.samsung.com> (raw)
In-Reply-To: <1464358702-19083-1-git-send-email-javier@osg.samsung.com>

The function can fail so the returned value should be checked
and the error propagated to the caller in case of a failure.
