From: Shivasharan S <[email protected]> commit b9d5e3e7f370a817c742fb089ac1a86dfe8947dc upstream.
MFI_BIG_ENDIAN macro used in drivers structure bitfield to check the CPU big endianness is undefined which would break the code on big endian machine. __BIG_ENDIAN_BITFIELD kernel macro should be used in places of MFI_BIG_ENDIAN macro.
