[PATCH 00/40] [Set 11] Rid W=1 warnings from GPU

[Lee Jones]

This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.

[PATCH 01/40] drm/nouveau/nvkm/subdev/bios/init: Demote obvious abuse of kernel-doc

[Lee Jones]

Fixes the following W=1 kernel build warning(s):

 drivers/gpu/drm/nouveau/nvkm/subdev/bios/init.c:584: warning: Function parameter or member 'init' not described in 'init_reserved'
 drivers/gpu/drm/nouveau/nvkm/subdev/bios/init.c:611: warning: Function parameter or member 'init' not described in 'init_done'
 drivers/gpu/drm/nouveau/nvkm/subdev/bios/init.c:622: warning: Function parameter or member 'init' not described in 'init_io_restrict_prog'
 drivers/gpu/drm/nouveau/nvkm/subdev/bios/init.c:659: warning: Function parameter or member 'init' not described in 'init_repeat'
 drivers/gpu/drm/nouveau/nvkm/subdev/bios/init.c:685: warning: Function parameter or member 'init' not described in 'init_io_restrict_pll'
 drivers/gpu/drm/nouveau/nvkm/subdev/bios/init.c:725: warning: Function parameter or member 'init' not described in 'init_end_repeat'

NB: Trimmed for brevity (lots of these!)
