[Why] when 4k@144hz dp connect to dp1.4 dsc mst hub, requested bandwidth exceeds caps of dsc hub. but dsc bw valid functions, increase_dsc_bpp, try_disable_dsc, pre_validate_dsc, compute_mst_dsc_configs_for_state, do not return false to atomic check. this cause user mode initiate mode set to kernel, then cause kernel assert, system hang. [How] dsc bandwidth valid functions return pass or fail to atomic check.

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.
