Subject: [PATCH] brcmfmac: remove unnecessary call to brcmf_sdiod_set_backplane_window()
Git-commit: c900072bd6faff089aa4fb7b19136a2a0fe3baf0
Patch-mainline: v4.16-rc1
References: FATE#326294
All functions that might require the window address changing call
brcmf_sdiod_set_backplane_window() prior to access. Thus resetting
the window is not required.
