Re: [PATCH] media: amd: isp4: fix self-deadlock in isp4sd_start_stream() error path

[Seifelden Abdelmonem]

Tested on an ASUS ROG Flow Z13 (GZ302EA) with v7.2.10 and an
out-of-tree setup in which the OV13B10 streams (NV12 1920x1080), with
this patch applied on top of my two isp4 fixes [1]:

- stream with the format set: 90 frames;
- stop, then stream again without setting the format: VIDIOC_STREAMON
  returns -EINVAL after "fail to get out prop" and "fail to setup
  output", v4l2-ctl exits and no task is left blocked;
- stream with the format set again: 90 frames.

No hung task, oops or WARN in the kernel log. I did not run the
sequence without the patch on this setup.
