Hello,
This v2 series fixes the use-after-free bug in mtk_jpeg_dec_device_run.
This patch fixes the security bug in chrome-os.
It inclues reverting the incomplete fix before and make the right fix.
Also,it fixes the error of timeout-worker-schedule in multiple-core
devices.
1. Remove cancel worker in mtk_jpeg_remove for the worker is only
registered in single-core device but we try to cacnel it in both
single-core and multiple-core devices.
2. Fix use-after-free bug by delay the schedule_delayed_work only if
mtk_jpeg_set_dec_dst runs successfully.
3. Delay the schedule_delayed_work in mtk_jpegdec_worker as it has same
code logic in mtk_jpeg_dec_device_run.
