Hi Jiri,
"led_set_func_hid_lenovo" is set to "hid_lenovo_led_set"
+#if IS_ENABLED(CONFIG_HID_LENOVO) +static int hda_fixup_thinkpad_hid_prepare(struct hda_codec *codec) +{ + struct hda_gen_spec *spec = codec->spec; + int ret = 0; + + if (!is_thinkpad(codec)) + return -ENODEV; + if (!led_set_func_hid_lenovo) + led_set_func_hid_lenovo = symbol_request(hid_lenovo_led_set);
"hid_lenovo_led_set" is introduced in "[PATCH v2 2/2] hda: thinkpad_helper: Add support for hid-lenovo LED control". This means that "[PATCH 4/4] hda: thinkpad_helper: Add support for hid-lenovo LED control" can only work with applied "[PATCH 1/4] hid-lenovo: Add support for X1 Tablet cover special keys" and "[PATCH v2 2/2] hda: thinkpad_helper: Add support for hid-lenovo LED control".
Best regards,

led_set_func_hid_lenovo(HID_LENOVO_LED_MUTE, !enabled);Where does led_set_func_hid_lenovo() come from? I don't see it in Linus' tree as of today. Is that something else than tpacpi_led_set()?
Thanks,
