Cc: Gerd Hoffmann Subject: [Qemu-devel] [PATCH v2 6/6] intel-hda: fix codec addressing. X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: qemu-devel.nongnu.org List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org The HDA bus supports up to 15 codecs, with addresses 0 ... 14. We get that wrong in two places: * When handing out addresses we accept address 15 as valid. * The bitmasks for two registers (WAKEEN and STATESTS) don't have bit 14 set. This patch fixes it.
