From a0747eb81c1d106b1408d60452af75cd17a67621 Mon Sep 17 00:00:00 2001 From: Shawn Lin Date: Mon, 14 Mar 2016 12:41:33 +0800 Subject: [PATCH] mmc: core: remove redundant memset of sdio_read_cccr When initializing sdio card, we get struct mmc_card from mmc_alloc_card which allocates it by kzalloc. So we don't need another memset while reading cccr.
