Krzysztof Kozlowski cfaa04a3ab soundwire: fix initializing sysfs for same devices on different buses ... [ Upstream commit 8a8a9ac8a4 ] If same devices with same device IDs are present on different soundwire buses, the probe fails due to conflicting device names and sysfs entries: sysfs: cannot create duplicate filename '/bus/soundwire/devices/sdw:0:0217:0204:00:0' The link ID is 0 for both devices, so they should be differentiated by the controller ID. Add the controller ID so, the device names and sysfs entries look like: sdw:1:0:0217:0204:00:0 -> ../../../devices/platform/soc@0/6ab0000.soundwire-controller/sdw-master-1-0/sdw:1:0:0217:0204:00:0 sdw:3:0:0217:0204:00:0 -> ../../../devices/platform/soc@0/6b10000.soundwire-controller/sdw-master-3-0/sdw:3:0:0217:0204:00:0 [PLB changes: use bus->controller_id instead of bus->id] Fixes: 7c3cd189b8 ("soundwire: Add Master registration") Cc: stable@vger.kernel.org Reviewed-by: Bard Liao <yung-chuan.liao@linux.intel.com> Reviewed-by: Vijendar Mukunda <Vijendar.Mukunda@amd.com> Co-developed-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Tested-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Acked-by: Mark Brown <broonie@kernel.org> Tested-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Link: https://lore.kernel.org/r/20231017160933.12624-3-pierre-louis.bossart@linux.intel.com Signed-off-by: Vinod Koul <vkoul@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>		2024-01-31 16:18:47 -08:00
