From 3e1a6892481034193b2502725f787465ebf39818 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Thu, 14 Nov 2013 10:16:20 +0200 Subject: [PATCH] mmc: sdhci: Allow for long command timeouts The driver has a timer with a 10 second timeout to catch devices that stop responding. However it is possible for commands to take even longer than that. Change the timer timeout to reflect the command timeout.
