Actually I have no idea about STA2x11, but in some thread I have noticed that
there were people who know more on the topic and they told that removal is the

Not sure how it should be done practically (driver-by-driver or altogether),
Acked-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
for either of the variants if it helps.
