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 >>):

btmtkuart.c:671:18: sparse:    warning: incorrect type in assignment
			       (different base types)
btmtkuart.c:671:18: sparse:    expected unsigned int [usertype] baudrate
btmtkuart.c:671:18: sparse:    got restricted __le32 [usertype]
