I just applied these two patches into staging tree and it seems to fix
dma mapping error. There is no trace dump in dmesg now.

However, I mistakenly assumed that dmesg trace was also only indicator
that SD card reader does not work. It seems like these two issues are
not connected, both 37fcacb50be7071d146144a6c5c5bf0194b9a1cf (last
commit that does not have trace dump) and this version after patch do
not register SD card.

I will do another bisect to find out which commit actually causes SD
card reader to not register SD cards. I will contact you after I do more
testing.
