Subject: [PATCH 08/14] mmc: mmci: add get_next_data callback
Date: Wed, 1 Aug 2018 11:36:55 +0200 [thread overview]
Message-ID: <1533116221-380-9-git-send-email-ludovic.Barre@st.com> (raw)
In-Reply-To: <1533116221-380-1-git-send-email-ludovic.Barre@st.com>
From: Ludovic Barre <ludovic.barre@st.com>
This patch adds get_next_data callback to mmci_host_ops.
Generic mmci_get_next_data factorizes next_cookie check and
the host ops call.
