From 0df9d2eae5e1092b07eaab6b989c2ff14115cab5 Mon Sep 17 00:00:00 2001 From: Takeshi Kihara Date: Mon, 20 Jul 2015 01:39:59 +0900 Subject: [PATCH] mmc: tmio: Fix timeout value for command request Fix the problem which timeout occurs at the time of command request with several cards. The timeout value was insufficient as a verification of several cards, so it was changed 5 seconds from 2 seconds.
