[ Upstream commit e60955dbecb97f080848a57524827e2db29c70fd ]
Sparse is not happy about misuse of bitwise types:
.../max3100.c:194:13: warning: incorrect type in assignment (different base types) .../max3100.c:194:13: expected unsigned short [addressable] [usertype] etx .../max3100.c:194:13: got restricted __be16 [usertype] .../max3100.c:202:15: warning: cast to restricted __be16
Fix this by choosing proper types for the respective variables.
