Subject: [PATCH 1/8] eeepc-laptop: flatten control flow
Date: Wed, 22 Oct 2014 21:12:36 +0200 [thread overview]
Message-ID: <1414005163-3461-2-git-send-email-fransklaver@gmail.com> (raw)
In-Reply-To: <1414005163-3461-1-git-send-email-fransklaver@gmail.com>
In eeepc_rfkill_hotplug there's an if statement with a big tail that
ends right before the out_unlock label. We might as well invert the
condition and jump to out_unlock in that case, pretty much like the rest
of the code does. This removes an indentation level for a large chunk of
code and also stops suggesting there might be an else clause.
