From 02769968d95b32e1d14e30b54dc57fe525c06d2b Mon Sep 17 00:00:00 2001 From: Ludovic Barre Date: Mon, 8 Oct 2018 14:08:37 +0200 Subject: [PATCH] mmc: mmci: add get_next_data callback 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.
