When e.g. wpa_supplicant sets only the MLD "sta" authorized
state, the code actually applies that change, but then returns
an error to userspace anyway because there were no changes to
the link station, and no link ID was given. However, it's not
incorrect to not have a link ID when wanting to change only
the MLD peer ("sta") state, so the code shouldn't require it.
To fix this, separate the "new_link" argument out into a new
three-state enum, because if modify is called on a link STA
only, it should return an error if no link is given or if it
doesn't exist. For modify on the MLD "sta", not having a link
ID is OK, but if there is one it should be validated.
This seems to not have mattered much as wpa_supplicant just
prints a message and continues, and the authorized state was
already set before this error return. However, in the later
code powersave recalculation etc. will be skipped, so that it
may result in never allowing powersave on MLO connections.

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 reStructuredText 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.
