From 5074d25dc97ac2d93fca7852563b7e204f03464a Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Tue, 13 Dec 2011 16:53:17 +0100 Subject: [PATCH] ARM: 7216/1: mmc: mmci: Do not release spinlock in request_end The patch "mmc: core: move ->request() call from atomic context", is the reason to why this change is possible. This simplifies the error handling code execution path quite a lot and potentially also fixes some error handling hang problems.
