SubjectRe: [PATCH 12/16] isdn: pcbit: fix interruptible_sleep_on race
From: Arnd Bergmann <>
Date: Wed, 26 Feb 2014 12:01:52 +0100

> interruptible_sleep_on is racy and going away. In case of pcbit,
> the driver would run into a timeout if the card is initialized
> before we start waiting for it. This uses wait_event to fix the
> race. In order to do this, the state machine handling for the
> timeout case has to get trivially reorganized so we actually know
> whether the timeout has occorred or not.
