[PATCH 01/26] drm/irq: Don't check for DRIVER_HAVE_IRQ in drm_irq_(un)install

Daniel Vetter
2019-01-24T16:58:06Z

If a non-legacy driver calls these it's valid to assume there is
interrupt support. The flag is really only needed for legacy drivers.

Also remove all the flag usage from non-legacy drivers.
