Subject: [PATCH 19/20] usb/gadget/udc: renesas: Use pm_ptr() macro
Date:   Thu,  3 Sep 2020 13:25:53 +0200
Message-Id: <20200903112554.34263-20-paul@crapouillou.net>
In-Reply-To: <20200903112554.34263-1-paul@crapouillou.net>
References: <20200903112554.34263-1-paul@crapouillou.net>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use the newly introduced pm_ptr() macro, and mark the suspend/resume
functions __maybe_unused. These functions can then be moved outside the
CONFIG_PM_SUSPEND block, and the compiler can then process them and
detect build failures independently of the config. If unused, they will
simply be discarded by the compiler.
