[Greg Kroah-Hartman]

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

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

From: Micky Ching <micky_ching@xxxxxxxxxxxxxx>

commit 5027251eced6e34315a52bd841279df957f627bb upstream.

a27fbf2f067b0cd ("mmc: add ignorance case for CMD13 CRC error") produced
a cmd.flags unhandled in realtek pci host driver.  This will make MMC
card fail to initialize, this patch is used to handle the new cmd.flags
condition and MMC card can be used.
