From 6b2221b008e0ea66de5befab38515e1a38c74d4f Mon Sep 17 00:00:00 2001 From: Andrew Gabbasov Date: Thu, 3 Apr 2014 04:34:32 -0500 Subject: mmc: Handle switch error status bit in MMC card status MMC switch command for unsupported feature (e.g. bus width) sets a switch error bit in card status. This bit should be checked, and, if it's set, no access with new controller settings should be performed.
