Subject: [PATCH 15/18][V3] ARM: OMAP3: cpuidle - simplify next_valid_state
Date: Tue, 24 Apr 2012 16:05:36 +0200 [thread overview]
Message-ID: <1335276339-11135-16-git-send-email-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <1335276339-11135-1-git-send-email-daniel.lezcano@linaro.org>
Simplify the indentation by removing the useless 'else' statement.
Remove the first loop for the 'idx' search as we have it already
with the 'index' passed as parameter.
