Subject: [RFC PATCH 3/2] mmc: renesas_sdhi: remove double clear of automatic correction
Date: Tue,  3 Dec 2019 21:33:01 +0100	[thread overview]
Message-ID: <20191203203301.2202-4-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20191203203301.2202-1-wsa+renesas@sang-engineering.com>

hw_reset() clears the automatic correction bit twice. I couldn't find
anything in the docs recommending that. Removing one of them didn't
cause any regressions here, so keep it simple.

Last minute patch, sorry for the confusing numbering...
