Include <linux/sizes.h> header that is missing after commit ab7ef22419
"[media] m5mols: Implement .get_frame_desc subdev callback".
It prevents possible build errors due to undefined SZ_1M.
This header is currently included only when m5mols is compiled
on arm; if build on other archs, the compilation will break.

Without the locking the driver's data could get corrupted when the subdev
is accessed from user space and from host driver by multiple processes.

Since all host drivers using this subdev are already using
the control framework these compatibility ops can be removed.

The result of one call to a function is tested, and then at the second call
to the same function, the previous result, and not the current result, is
tested again.
The semantic match that finds this problem is as follows:
