Subject: [PATCH 1/2] mmc: tmio: add generic hook to fixup after a completed request
Date: Fri,  5 Jun 2020 12:12:21 +0200	[thread overview]
Message-ID: <20200605101222.10783-2-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20200605101222.10783-1-wsa+renesas@sang-engineering.com>

Sadly, due to HW bugs, we need a callback to work around issues just
before completing the request.
