[ Upstream commit cac63f9b163700fb70a609ad220697c61b797d6b ]

Fixed warning: incorrect type in assignment reported by kbuild test robot.
The detailed warning is shown as below.

make ARCH=x86_64 allmodconfig
make C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'

All warnings (new ones prefixed by >>):
