Subject: [PATCH] arm/komeda: Compile komeda_debugfs_init() only if CONFIG_DEBUG_FS is enabled
Date:   Mon, 25 Mar 2019 17:01:14 +0000
Message-Id: <20190325170114.20407-1-Liviu.Dudau@arm.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

We don't call this function if CONFIG_DEBUG_FS is not defined, but we
should not be compiling it either, as the declaration of the debugfs
core functions is not included.

Reported by the kbuild test robot.
