Subject: [PATCH] ASoC: tas2552: Fix compilation warning for !PM_RUNTIME
Date: Thu, 2 Oct 2014 09:28:00 +0200 [thread overview]
Message-ID: <1412234880-8308-1-git-send-email-thierry.reding@gmail.com> (raw)
From: Thierry Reding <treding@nvidia.com>
The tas2552_sw_shutdown() function is only used by runtime suspend
support, so only build it when necessary.
