Subject: [PATCH v6 2/3] media: test-drivers: Use V4L2_FMTDESC_FLAG_ENUM_ALL flag
Since the V4L2_FMTDESC_FLAG_ENUM_ALL flag mostly targets stateless
decoder pixel-format enumeration, update visl test driver to use it.
When V4L2_FMTDESC_FLAG_ENUM_ALL flag is set let the driver returns
one more pixel format.
Signed-off-by: Benjamin Gaignard <benjamin.gaignard@...labora.com>

change in version 6:
- Improve visl driver to enumerate one more pixel format when the flag
is used.
