Subject: [ 028/173] Revert misapplied "mmc: sh-mmcif: avoid oops on spurious interrupts"

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chris Ball <cjb@...top.org>

commit 6984f3c31bb57cb7491dbec1be44b74bd00f4648 upstream.

This reverts commit 8464dd52d3198dd05, which was a misapplied debugging
version of the patch, not the final patch itself.
