[ Upstream commit6d020d81b9] Given that only the MM21 capture format is supported by userspace tools (like gstreamer and libyuv), make it the default capture format. This allows us to force the MM21 format even when a MM21 and MT21C capable firmware is available (which is needed while dynamic format switching isn't implemented in the driver), without causing the following regressions on v4l2-compliance: fail: v4l2-test-formats.cpp(478): pixelformat 3132544d (MT21) for buftype 9 not reported by ENUM_FMT test VIDIOC_G_FMT: FAIL fail: v4l2-test-formats.cpp(478): pixelformat 3132544d (MT21) for buftype 9 not reported by ENUM_FMT test VIDIOC_TRY_FMT: FAIL fail: v4l2-test-formats.cpp(478): pixelformat 3132544d (MT21) for buftype 9 not reported by ENUM_FMT test VIDIOC_S_FMT: FAIL Fixes:7501edef6b("media: mediatek: vcodec: Different codec using different capture format") Signed-off-by: Yunfei Dong <yunfei.dong@mediatek.com> Reviewed-by: Nicolas F.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
