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.

•   ret = request_irq(priv->vsync_irq, meson_irq, 0, drm->driver->name, drm);
  

I'd like to use dev_name(dev) instead of drm->driver->name in the future as that'll make it much easier to identify the corresponding IRQ in /proc/interrupts for example your patch makes this possible - thanks for this!

Best regards, Martin
