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

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

[Daniel Vetter]

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.

The actual code changes looks good.
But if this is the right thing to do I cannot tell.

On this (limited) basis I provide an:

I'd add a bit more information here. Feel free to reuse as much/little

... legacy drivers which issue the IRQ via the DRM_IOCTL_CONTROL legacy IOCTL.

At a later stage, we might as well add LEGACY to the name:
DRIVER_LEGACY_HAVE_IRQ?

Local grep shows one more non-legacy entry in
drivers/gpu/drm/hisilicon/hibmc/hibmc_drm_drv.c

With that file addressed and trivial comment additions, patches: 1, 2,
