drm: vmwgfx: remove drm_driver::master_set() return type
The function always returns zero (success). Ideally we'll remove it all together - although that's requires a little more work. For now, we can drop the return type and simplify the drm core code surrounding it. v2: remove redundant assignment (Sam) Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: VMware Graphics <linux-graphics-maintainer@vmware.com> Cc: Roland Scheidegger <sroland@vmware.com> Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com> Cc: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Roland Scheidegger <sroland@vmware.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200530124640.4176323-1-emil.l.velikov@gmail.com
