Subject: [patch 1/2] staging: ath6kl: cleanup in SEND_FRAME ioctl
Date: Sun, 20 Feb 2011 12:49:08 +0000	[thread overview]
Message-ID: <20110220124832.GA1898@bicker> (raw)

The original code was written in a funny way where every statement was
part of else if blocks.  I broke them up into separate statements by
adding breaks on failure conditions.
