Oh, just when I committed the patch. But thanks for your reply.
[...]- ret = drm_irq_install(drm, priv->vsync_irq); + 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!
I also thought about this, but every driver in DRM and apparently most drivers in general pass the driver's name here. I think the change would make a lot of sense, but it's probably worth a kernel-wide effort.
Best regards Thomas
