ext2: Fix checkpatch violations
Fix all checkpatch violations in the low level Ext2 block device reading code. This is done in preparation for cleaning up the partial sector access code. Signed-off-by: Anton Staaf <robotboy@chromium.org> Cc: Andy Fleming <afleming@freescale.com> Acked-by: Detlev Zundel <dzu@denx.de>
