[PATCH][next] drm/amd/display: Fix fall-through warning for Clang

2021-06-16 Thread Gustavo A. R. Silva
In preparation to enable -Wimplicit-fallthrough for Clang, fix
the following warning by replacing a /* fall through */ comment
with the new pseudo-keyword macro fallthrough:

rivers/gpu/drm/amd/amdgpu/../display/dc/dce/dce_aux.c:672:4: warning: 
unannotated fall-through between switch labels [-Wimplicit-fallthrough]
case AUX_TRANSACTION_REPLY_I2C_OVER_AUX_DEFER:
^

Notice that Clang doesn't recognize /* fall through */ comments as
implicit fall-through markings, so in order to globally enable
-Wimplicit-fallthrough for Clang, these comments need to be
replaced with fallthrough; in the whole codebase.

JFYI: We had thousands of these sorts of warnings and now we are down
  to just 15 in linux-next. This is one of those last remaining
  warnings.
