From 66656020ff180e2a689fbe83fcd02c3e42ecdc30 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 23 Apr 2017 20:02:09 -0600 Subject: dm: mmc: Check that drivers have operations When binding a new MMC device, make sure that it has the required operations. Since for now we still support *not* having the operations (with CONFIG_DM_MMC_OPS not enabled) it makes sense to add this check.
