On i.MX8MP, when the TERE and FSD_MSTR enabled before configuring
the word width, there will be no frame sync clock issue, because
old word width impact the generation of frame sync.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

Hello,
this patch set converts the platform drivers below drivers/usb/gadget to
use .remove_new. These drivers all have an error path if the driver is
still in use. Returning there early leaks resources, but fixing this
isn't trivial, so I just added an error message. The patches don't make

Low power audio mode requires binding codec still power on while Acore
enters into suspend so Mcore can continue playback music.
ASoC machine driver acquires DAPM endpoints through reading
"ignore-suspend-widgets" property from DT and then forces the path
between these endpoints ignoring suspend.
Add a property to list audio sound widgets which are marked ignoring
system suspend. Paths between these endpoints are still active over
suspend of the main application processor that the current operating
system is running.
