Slowackiego 173, 80-298 Gdansk Subject: [Intel-gfx] [PATCH 04/10] drm/i915/uc: Move intel_uc_fw_fetch() to intel_uc.c 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 The file fits better. Additionally rename it to intel_uc_prepare_fw(), as the function does more than simple fetch.
