ieee80211_iterate_active_interfaces() and ieee80211_iterate_active_interfaces_atomic() already exist, where the former allows the iterator function to sleep. Add ieee80211_iterate_stations() which is similar to ieee80211_iterate_stations_atomic() but allows the iterator to sleep. This is needed for adding SDIO support to the rtw88 driver. Some interators there are reading or writing registers. With the SDIO ops (sdio_readb, sdio_writeb and friends) this means that the iterator function may sleep.

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.
