[U-Boot] [PATCH v2 1/2] ext2: Fix checkpatch violations

Thu Jun 30 20:45:36 CEST 2011


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.

Also replace hard coded function names in printfs with __func__
macro, and correctly indent comments for style consistency
not captured by checkpatch.
