Subject: [PATCH 5.4 460/475] mmc: mmci_sdmmc: Replace sg_dma_xxx macros

From: Ludovic Barre <ludovic.barre@...com>

commit 127e6e98ca9b8ac4f87698ebce1508e3449bb791 upstream.

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.
