Subject: [PATCH V2 1/6] PM / QOS: Add default case to the switch
Date: Thu,  9 Feb 2017 09:11:47 +0530	[thread overview]
Message-ID: <338b16e4c882634e30e4f4c011a9e9c52d134cbc.1486611268.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1486611268.git.viresh.kumar@linaro.org>
In-Reply-To: <cover.1486611268.git.viresh.kumar@linaro.org>

The switch block handles all the QOS request types present today, but
starts giving compilation warnings as soon as a new type is added and
not handled in this.

To prevent against that, add the default case as well and do a WARN from
it.
