From 5027251eced6e34315a52bd841279df957f627bb Mon Sep 17 00:00:00 2001 From: Micky Ching Date: Thu, 27 Mar 2014 13:35:04 +0800 Subject: [PATCH] mmc: rtsx: add R1-no-CRC mmc command type handle 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.
