[PATCH 5.6 135/161] scsi: megaraid_sas: Replace undefined MFI_BIG_ENDIAN macro with __BIG_ENDIAN_BITFIELD macro
From: Greg Kroah-Hartman
Date: Tue Jun 16 2020 - 11:56:18 EST
From: Shivasharan S <shivasharan.srikanteshwara@xxxxxxxxxxxx>
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.
