When play a SDR video after HDR video, there is a switch process, look from 70.769811 seconds to 71.006901 seconds: The HDMI was set to SDR(vcstate->eoftf = 0), the Plane is still HDR (vpstate->eotf = 2), this will set the window to HDR2SDR state, but actually we want play a sdr video in sdr state, and this cause the wrong csc. So we clear vpstate->hdr2sdr_en & hdr_in at the beginning of every commit.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
