Commit 9697dffb098d ("drm: Turn off Legacy Context Functions") added checks for legacy features to several functions in the drm driver. It is now possible for the void functions changed by this commit to return an int error code. This patch updates the function definitions to return int. This fixes the build warnings:
warning: ‘return’ with a value, in function returning void return -EINVAL

Oops sorry, I spotted this while applying but somehow screwed up and still pushed out the patch. Dropped it now for real.
Thanks, Daniel
