Subject: [PATCH] ASoC: codecs: PCM1789: unconditionally flush work
Date:   Sun, 17 Jun 2018 15:45:29 +0200
Message-Id: <20180617134532.1070-1-stefan@agner.ch>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Work is guaranteed to be initialized on exit. Drop the unnecessary
if statement and always call flush_work.

This fixes a warning seen with clang:
sound/soc/codecs/pcm1789.c:265:13: warning: address of 'priv->work' will
      always evaluate to 'true' [-Wpointer-bool-conversion]
        if (&priv->work)
        ~~   ~~~~~~^~~~
