Kalle Valo says:

====================
wireless-drivers-next patches for v5.15

First set of patches for v5.15. This got delayed as I have been mostly
offline for the last few weeks. The biggest change is removal of
prism54 driver, otherwise just smaller changes.

Major changes:

ath5k, ath9k, ath10k, ath11k:

* switch from 'pci_' to 'dma_' API

brcmfmac

* allow per-board firmware binaries

* add support 43752 SDIO device

prism54

* remove the obsoleted driver, everyone should be using p54 driver instead
====================
