Subject: drm/ttm: use cancel_delayed_work_sync() in ttm_bo
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f094cfc6c382cec7b2c77dd7798576684153acbb;p=linux-beck.git

drm/ttm: use cancel_delayed_work_sync() in ttm_bo

Make ttm_bo::ttm_bo_device_release call cancel_delayed_work_sync()
instead of calling cancel_delayed_work() followed by
flush_scheduled_work().

This is to prepare for the deprecation and removal of
flush_scheduled_work().
