Subject: [PATCH] drm/nouveau: use proper prototype in nouveau_pmops_runtime() definition
Git-commit: 5499473c86503bb8e307ff7b554643a99a9478c2
Patch-mainline: v4.13-rc1
References: bsc#1051510

There is a prototype for this function in the header, but the function
itself lacks a 'void' in the argument list, causing a harmless warning
when building with 'make W=1':

Drivers/gpu/drm/nouveau/nouveau_drm.c: In function 'nouveau_pmops_runtime':
drivers/gpu/drm/nouveau/nouveau_drm.c:730:1: error: old-style function definition [-Werror=old-style-definition]

Fixes: 321f5c5f2c49 ("drm/nouveau: replace multiple open-coded runpm support checks with function")
