Subject: [PATCH] mac80211: small tx code cleanup
Date: Mon, 10 Aug 2009 16:04:15 +0200 [thread overview]
Message-ID: <1249913055.32614.6.camel@johannes.local> (raw)
It's really easier to read if it's not indented
as much, so invert the condition and rearrange
the code so the smaller chunk is indented instead.
