In order to get regulatory domain, driver sends MCC_UPDATE_CMD to the FW. One of the parameters in the response is the status which can tell if the regdomain has changed or not. When iwl_mvm_init_mcc() is called during iwl_op_mode_mvm_start(), then sband is still NULL and channel parameters (i.e. chan->flags) cannot be initialized. When, further in the flow, iwl_mvm_update_mcc() is called during iwl_mvm_up(), it first checks if the regdomain has changed and then skips the update if it remains the same. But, since channel parameters weren't initialized yet, the update should be forced in this codepath. Fix that by adding a corresponding parameter to iwl_mvm_init_fw_regd().

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.
