[PATCH] init/do_mounts.c: treat EROFS like EACCES
From: Philippe De Muyter
Date: Wed Jun 18 2014 - 12:22:14 EST
some combinations of filesystem and block device (at least vfat on mmc)
yield -EROFS instead of -EACCES when the device is read-only. Retry
mounting with MS_RDONLY set, just like for the EACCES case, instead of
failing directly.
