Subject: [051/107] mmc: tmio: fix regression in TMIO_MMC_WRPROTECT_DISABLE handling

2.6.39-stable review patch.  If anyone has any objections, please let us know.

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

From: Guennadi Liakhovetski <g.liakhovetski@....de>

commit 7d8b4c2a4b73da8e3632603691838ca5b2a8c26d upstream.

Commit b6147490e6aac82 ("mmc: tmio: split core functionality, DMA and
MFD glue") broke handling of the TMIO_MMC_WRPROTECT_DISABLE flag by
the tmio-mmc driver. This patch restores the original behaviour.
