[U-Boot] [PATCH 1/2] common/cmd_ide.c: CodingStyle cleanup
Wolfgang Denk
wd at denx.de
Sat Oct 29 21:41:40 CEST 2011
Make file acceptable to checkpatch.
This is only a basic clean up to the extend possible without any real
changes to the source code. Warnings due to line over 80 characters
were accepted because these affect only printf()s with user visible
strings. No attempts were made to fix warnings about volatile and
externs - these need a more thorough cleanup.
