[PATCH v2 0/2] media: venus: fix HFI teardown races

[mhun512]

As part of our ongoing static-analysis research, we reviewed the Venus
teardown path and confirmed the race reported by Sashiko.

This series fixes two HFI lifetime races during teardown. The first patch
waits for the hard and threaded IRQ handlers before releasing HFI state.
The second disables and drains recovery work so it cannot be requeued
while HFI state is being torn down.

The later Sashiko report also identifies a separate resource leak when IRQ
registration fails during probe. That issue is outside this series.

Changes in v2:
- Resend the same changes using git format-patch and git send-email so each
  diff --git header stays on one line. The v1 mail transport wrapped those
  headers and prevented git am from parsing the patches.
