Hi, this is patch series I've hacked after useful conversation with Pavel. Basically this adds a new LED trigger audio-mute and audio-micmute, and convert the HD-audio driver and the platform drivers to use the LED trigger instead of the ugly direct dynamic symbol binding. The latest version of patches are found in topic/leds-trigger branch in my sound git tree. git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git As these are cross-tree patches, the branch above is based cleanly on v4.20-rc3, so that it can be merged well to multiple trees. Once after getting the ACK's, I'll add tags and fixate for merges. This patch series don't include huawei-wmi stuff; so Huawei patches need rework. I already have some piece of changes for huawei-wmi, so please ping me if needed. I checked briefly on my Dell laptop, and a Thinkpad model. Wider tests are appreciated, of course. thanks, Takashi === Takashi Iwai (6): leds: trigger: Introduce audio mute LED trigger platform/x86: dell-laptop: Add micmute LED trigger support platform/x86: thinkpad_acpi: Add audio mute LED classdev support ALSA: hda - Support led audio trigger platform/x86: dell-laptop: Drop superfluous exported function platform/x86: thinkpad_acpi: Drop superfluous exported function drivers/leds/trigger/Kconfig | 7 +++ drivers/leds/trigger/Makefile | 1 + drivers/leds/trigger/ledtrig-audio.c | 45 +++++++++++++++++++ drivers/platform/x86/Kconfig | 4 ++ drivers/platform/x86/dell-laptop.c | 27 +++++++++--- drivers/platform/x86/thinkpad_acpi.c | 66 +++++++++++++++++++++------- include/linux/dell-led.h | 7 --- include/linux/leds.h | 20 +++++++++ include/linux/thinkpad_acpi.h | 16 ------- sound/pci/hda/dell_wmi_helper.c | 48 -------------------- sound/pci/hda/hda_generic.c | 31 +++++++++++++ sound/pci/hda/hda_generic.h | 2 + sound/pci/hda/patch_realtek.c | 17 +++---- sound/pci/hda/thinkpad_helper.c | 43 +++--------------- 14 files changed, 194 insertions(+), 140 deletions(-) create mode 100644 drivers/leds/trigger/ledtrig-audio.c delete mode 100644 include/linux/dell-led.h delete mode 100644 include/linux/thinkpad_acpi.h delete mode 100644 sound/pci/hda/dell_wmi_helper.c -- 2.19.1
