From ca4e7d674ee6931c7a4effd697e644d7646cfac0 Mon Sep 17 00:00:00 2001 From: Matt Pelland Date: Mon, 16 Apr 2018 10:08:18 -0400 Subject: [PATCH] mmc: mv_sdhci: zero out sdhci_host structure The mv_sdhci driver was not zeroing the sdhci_host structure it allocates causing random access violations in parts of the mmc core where the "ops" member pointers are checked and called if not NULL.
