I see. What I checked yesterday is not MeeGo kernel code and caused some mis-understanding on this. Now, I think this patch is OK but just want to confirm that did you have tested it on MRST Langwell B0 and Langwell C0 platform? I recalled that seems Langwell B0 does not support 8bit bus width. So, maybe it needs to check Silicon version first before set the MMC_CAP_8_BIT_DATA cap bit, right? Thanks.
