Linux kernel source tree

Currently regulatory update by driver is not allowed when the wiphy->regd is already set and drivers_request->intersect is false. During wiphy registration, some drivers (ath10k does this currently) first register the world regulatory to cfg80211 using wiphy_apply_custom_regulatory(). The driver then obtain the current operating country and tries to update the correct regulatory to cfg80211 using regulatory_hint(). But at this point, wiphy->regd is already set to world regulatory. Also, since this is the first request from driver after the world regulatory is set this will result in drivers_request->intersect set to false. In this condition the driver request regulatory is not allowed to update to cfg80211 in reg_set_rd_driver(). This restricts the device operation to the world regulatory. This driver request to update the regulatory with current operating country is valid and should be updated to cfg80211. Hence allow regulatory update by driver even if the wiphy->regd is already set and driver_request->intersect is false.

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.
