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

From: Philipp Hortmann
Date: Fri Jul 29 2022 - 04:14:31 EST


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.

V1 -> V2: Combind patch "Rename dwData to reg_value ..." with this one
