Reg. #1134945 - Pipers Way, Swindon SN3 1RJ Subject: [Intel-gfx] [PATCH v5 06/11] drm/i915: tidy initialisation failure paths (legacy, part 2) X-BeenThere: intel-gfx@lists.freedesktop.org X-Mailman-Version: 2.1.18 Precedence: list List-Id: Intel graphics driver community testing & development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , MIME-Version: 1.0 Errors-To: intel-gfx-bounces@lists.freedesktop.org Sender: "Intel-gfx" X-Spam-Status: No, score=-4.5 required=5.0 tests=BAYES_00, RCVD_IN_DNSWL_MED, RP_MATCHES_RCVD, UNPARSEABLE_RELAY autolearn=unavailable version=3.3.1 X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on mail.kernel.org X-Virus-Scanned: ClamAV using ClamSMTP After the last patch, there is only one caller of the trivial function intel_destroy_ringbuffer_obj(), so we might as well fold it into the caller. v3: Don't bother to clear a pointer in an object about to be freed. [Chris Wilson] v4: Don't bother to check for NULL pointer, as drm_gem_object_unreference can handle NULL [Chris Wilson]. This relies on 'base' being the very first member of 'struct intel_ringbuffer'!
