Latest Thinkpad laptops use the HKEY_HID LEN0268 instead of the LEN0068, as a result neither audio mute led nor mic mute led can work any more. After adding the new HKEY_HID into the is_thinkpad(), both of them works well as before. Cc: <stable@xxxxxxxxxxxxxxx> Signed-off-by: Hui Wang <hui.wang@xxxxxxxxxxxxx> --- And the fix for thinkpad_acpi.c already sent out, and got ACK, please refer to: https://sourceforge.net/p/ibm-acpi/mailman/message/35478616/ Acctually we don't need to wait thinkpad_acpi.c to be patched first, since no matter the thinkpad_acpi.c merge that patch or not, the led control function is always provided by thinkpad_acpi.c, the new HKEY_ID only affects the automatic insmod for thinkpad_acpi.ko. sound/pci/hda/thinkpad_helper.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/sound/pci/hda/thinkpad_helper.c b/sound/pci/hda/thinkpad_helper.c index 6a23302..4d9d320 100644 --- a/sound/pci/hda/thinkpad_helper.c +++ b/sound/pci/hda/thinkpad_helper.c @@ -13,7 +13,8 @@ static bool is_thinkpad(struct hda_codec *codec) { return (codec->core.subsystem_id >> 16 == 0x17aa) && - (acpi_dev_found("LEN0068") || acpi_dev_found("IBM0068")); + (acpi_dev_found("LEN0068") || acpi_dev_found("LEN0268") || + acpi_dev_found("IBM0068")); } static void update_tpacpi_mute_led(void *private_data, int enabled) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
