Subject: [PATCH] drm/meson: Convert to Linux IRQ interfaces
Date: Tue,  6 Jul 2021 09:45:45 +0200	[thread overview]
Message-ID: <20210706074545.8763-1-tzimmermann@suse.de> (raw)

Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's
IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers
don't benefit from using it.
