Subject: [PATCH v3 1/4] devres: constify p in devm_kfree()
Date:   Mon, 24 Sep 2018 12:11:47 +0200
Message-Id: <20180924101150.23349-2-brgl@bgdev.pl>
In-Reply-To: <20180924101150.23349-1-brgl@bgdev.pl>
References: <20180924101150.23349-1-brgl@bgdev.pl>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Make devm_kfree() signature uniform with that of kfree(). To avoid
compiler warnings: cast p to (void *) when calling devres_destroy().
