Subject: [PATCH v2 1/5] staging: vt6655: Convert macro MACvReceive0 to
 function

Convert macro to static function. Multiline macros are not liked by
kernel community. Rename variable dwData to reg_value to avoid
CamelCase which is not accepted by checkpatch.pl. Change variable
declaration to u32 as this improves readability.
