[alsa-devel] [PATCH 4/4] hda: thinkpad_helper: Add support for hid-lenovo LED control

[Dennis Wassenberg]

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,

Dennis
