Slowackiego 173, 80-298 Gdansk Subject: [Intel-gfx] [PATCH 05/10] drm/i915/uc: Introduce intel_uc_init_fw() 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-Virus-Scanned: ClamAV using ClamSMTP Instead of calling intel_guc_init() and intel_huc_init() one by one this patch introduces intel_uc_init_fw() function that calls them both. Called functions are renamed accordingly. Trying to have subject_verb_object ordering and more descriptive names, the intel_huc_init() and intel_guc_init() functions are renamed. For guc_init(): * `intel_guc` is the subject, so those functions now take intel_guc structure, instead of the dev_priv * init is the verb * fw is the object which better describes the function's role huc_init() change follows the same reasoning. v2: settle on intel_uc_fetch_fw name (M. Wajdeczko) v3: yet another rename - intel_uc_init_fw (J.
