[PATCH 1/3] drm: drm_vm: Use fallthrough;

[Joe Perches]

Convert /* fallthrough */ style comments to fallthrough;

Convert the various uses of fallthrough comments to fallthrough;

Done via script
Link: https://lore.kernel.org/lkml/b56602fcf79f849e733e7b521bb0e17895d390fa.1582230379.git.joe@xxxxxxxxxxx/

And by hand:

This file has a fallthrough comment outside of an #ifdef block
that causes gcc to emit a warning if converted in-place.

So move the new fallthrough; inside the containing #ifdef/#endif too.
