We do call brcmf_sdiod_set_backplane_window() in this function. We just dont need to call it a second time to restore the original window. It may have been required in the past because the code relied on a value not changing (swbadr) which was a poor assumption. In practice, the current code does not provoke this potential bug, which I remove all possibility of happening in patch 23/30 -Ian
