While the endiannes is being handled correctly sparse was unhappy with
the missing annotation as be16_to_cpu() expects a __be16.

Problem reported by sparse
As far as I understand sparse here the __force is actually the only
solution possible to inform sparse that the endiannes handling is ok
Patch was compile-tested with. x86_64_defconfig + FIELDBUS_DEV=m,
HMS_ANYBUSS_BUS=m
Patch is against 5.1-rc6 (localversion-next is next-20190426)
