From 99ba04053a3712498327bd147c22a9877100a904 Mon Sep 17 00:00:00 2001 From: Nicolas Ferre <nicolas.ferre@atmel.com> Date: Thu, 27 Nov 2008 17:23:49 +0100 Subject: [PATCH] mmc: at91_mci: reorder timer setup and mmc_add_host() call As said in function comment mmc_add_host() requires that: "The host must be prepared to start servicing requests before this function completes." During this function, at91_mci_request() can be invoqued without timer beeing setup leading to a kernel Oops. This has been reported inserting this driver as a module.
