>Subject: [PATCH] drm: HACK: Do not start the polling within poll_init()
>
>Drivers from now needs to explicitly enable the poll when they need it.
>The only driver needs the polling to be disabled after it has been
>initialized is nouveau, which relied on the fact that in the past the work
>to do the actual poll was delayed by 10 seconds.
