Subject: [PATCH 6/7] pinctrl: msm: Remove impossible WARN_ON()s
Date: Thu,  6 Mar 2014 22:44:45 -0800	[thread overview]
Message-ID: <1394174686-8358-7-git-send-email-sboyd@codeaurora.org> (raw)
In-Reply-To: <1394174686-8358-1-git-send-email-sboyd@codeaurora.org>

All these functions are limited in what they can pass as the gpio
or irq number to whatever is setup during probe. Remove the
checks.
