Message

3 bug fixes found in rkisp1-params.c related to managing the vb2 buffers.

Testing:
--------

A test that streams the selfpath and params entities simultaneously
can be found in this branch of v4l-utils:
https://gitlab.collabora.com/dafna/v4l-utils/-/tree/params-bug-fixes

In the repo:
$ cd contrib/test
$ python3 test-rkisp1.py -t RKISP1_TEST_simple_stream_with_params -o /root -S -v --params-buf params-buf.dat

Dafna Hirschfeld (3):
  media: staging: rkisp1: params: don't reference the vb2 buffer after
    calling vb2_buffer_done
  media: staging: rkisp1: params: don't release lock in isr before
    buffer is done
  media: staging: rkisp1: params: in 'stop_streaming' don't release the
    lock while returning buffers
