I don't think I explained my point well. The description of this patch implies that this method brcmf_sdiod_ramrw(), now relies on the window being set elsewhere before it's called. I'm asking why we can't move the setting of the window inside this function and remove any redundant calls to brcmf_sdiod_set_backplane_window() outside of it.
