[Intel-gfx] [PATCH 09/10] drm/i915: Add intel_modeset_probe_defer() helper

2021-10-05 Thread Hans de Goede
The upcoming privacy-screen support adds another check for
deferring probe till some other drivers have bound first.

Factor out the current vga_switcheroo_client_probe_defer() check
into an intel_modeset_probe_defer() helper, so that further
probe-deferral checks can be added there.

Seems fine. Presumably Jani isn't too grumpy about it :P
