From 0b8c0e9c3354953a5d6f90ece82961017053dc74 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 13 Jul 2016 18:34:44 +0100 Subject: [PATCH] drm/i915/fbdev: Drain the suspend worker on retiring Since the suspend_work can arm itself if the console_lock() is currently held elsewhere, simply calling flush_work() doesn't guarantee that the work is idle upon return. To do so requires using cancel_work_sync().
