Baochen Qiang 52f8c45fa3 wifi: ath12k: support default regdb while searching board-2.bin for WCN7850
Sometimes board-2.bin does not have the regdb data which matches the
parameters such as vendor, device, subsystem-vendor, subsystem-device
etc. Add default regdb data with only 'bus=%s' into board-2.bin for
WCN7850, then ath12k uses 'bus=pci' to search regdb data in board-2.bin
for WCN7850.

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.
