Subject: [PATCH] brcmfmac: Register sizes on hardware are not dependent on compiler types
Git-commit: 1e6f676f43aa4270ebc5cff8e32a55f72362e042
Patch-mainline: v4.16-rc1
References: FATE#326294

The 4 IO functions in this patch are incorrect as they use compiler types
to determine how many bytes to send to the hardware.
