[Nouveau] [PATCH][next] drm/nouveau: Use fallthrough pseudo-keyword
Gustavo A. R. Silva
gustavoars at kernel.org
Tue Jul 7 17:31:02 UTC 2020
Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.
