A PCM capture stream on usb-audio causes a scheduling-while-atomic

snd_usb_endpoint_start() is called at first at trigger START for a

because the function is called at PCM prepare time, which can sleep.

ALSA: hda - Fix mute-LED GPIO initialization for IDT codecs
The IDT codecs initializes the GPIO setup for mute LEDs via
snd_hda_sync_vmaster_hook(). This works in most cases except for the
very first call, which is called before PCM and control creations.
Thus before Master switch is set manually via alsactl, the mute LED
may show the wrong state, depending on the polarity.
Now it's fixed by calling the LED-status update function manually when
no vmaster is set yet.

The root cause is that we still call snd_soc_dapm_new_widgets in
