Subject: [PATCH V2 1/9] mmc: mmci: sdmmc: replace sg_dma_xxx macros
Date: Tue, 28 Jan 2020 10:06:28 +0100 [thread overview]
Message-ID: <20200128090636.13689-2-ludovic.barre@st.com> (raw)
In-Reply-To: <20200128090636.13689-1-ludovic.barre@st.com>
sg_dma_xxx should be used after a dma_map_sg call has been done
to get bus addresses of each of the SG entries and their lengths.
But mmci_host_ops validate_data can be called before dma_map_sg.
This patch replaces theses macros by sg->offset and sg->length
which are always defined.
