I want to keep same behavior with alc_fixup_thinkpad_apci() and alc_fixup_idea_acpi() for one sound card. So, I add alc_fixup_no_shutup() in alc_fixup_ideapad_acpi().
----------Related source code of patch_reatek.c are FYR as below.
static void alc_fixup_thinkpad_acpi(struct hda_codec *codec,
const struct hda_fixup *fix, int
action)
{
alc_fixup_no_shutup(codec, fix, action); /* reduce click noise */
hda_fixup_thinkpad_acpi(codec, fix, action); }
/* for hda_fixup_ideapad_acpi() */
#include "ideapad_hotkey_led_helper.c"
static void alc_fixup_ideapad_acpi(struct hda_codec *codec,
const struct hda_fixup *fix, int action) {
alc_fixup_no_shutup(codec, fix, action); /* reduce click noise */
hda_fixup_ideapad_acpi(codec, fix, action);
}
Oh yeah, but then it can be bad in other way round; the chain call of
alc_fixup_thinkpad_acpi() contains alc_fixup_no_shutup() and the
alc_fixup_ideadpad_acpi() also contains alc_fixup_no_shutup().
That is, alc_fixup_no_shutup() will be called twice for Thinkpad.
Many thanks to Takashi for your detail comments and sample code, I
understand it now.
I'll check the logic of the code and update the patch later.

Since hda_fixup_ideapad_acpi() is NOP except for Ideapad, this
shouldn't break other models, while it covers the Ideadpad now.
