From a61ad2b49bfce94dfddce828cd9222e4b9e7825b Mon Sep 17 00:00:00 2001 From: Chris Ball Date: Wed, 13 Apr 2011 23:46:05 -0400 Subject: [PATCH] mmc: initialize struct mmc_data at declaration time Converts from: struct mmc_data data; memset(&data, 0, sizeof(struct mmc_data)); to: struct mmc_data data = {0}; because it's shorter, as performant, and easier to work out whether initialization has happened.
