Not sure if the following from the previous version is still needed as it was for a corner use case:

? 2024-12-26 - fix I_am_really_a_filesystem (see patch for explanation)

The plan is to support API changes through kernel 7.0 (for Ubuntu 26.04 LTS), after that, needed API fixes or additional capability will be up to the community as the new rtw89_8852bu in-kernel driver should meet the need on kernels 7.1+. This driver is primarily for users of older kernels that do not have the in-kernel driver.
