Subject[PATCH v2,0/7] media: mediatek: vcodec: Fix power_VideoCall test fail
Date
Random getting below error message when test power_VideoCall/control.49_vp9:
pc : __list_del_entry_valid+0xb0/0xfc
lr : __list_del_entry_valid+0xac/0xfc

The lat_buf in core list won't be deleted when one instance decode done.
Will access invalid released lat_buf list when queue work continue to decode.
Firstly, remove all unused lat_buf to the top of core list, making sure
these buffers can be decoded in highest priority; lastly, remove all unused
lat_buf when the instance is freed.

patch 1 add params to record lat and core lat_buf count.
patch 2 using each instance lat_buf count replace core ready list.
patch 3 move lat_buf to the top of core list.
patch 4 add core decode done event.
patch 5 remove unused lat_buf.
patch 6 making sure queue_work successfully
patch 7 change lat thread decode error condition
---
changed with v1:
- remove mutex for atomic for patch 1
- add patch 6 to make sure queue_work successfully
- add patch 7 change lat thread decode error condition
