[PATCH v2 2/2] staging: vt6655: Convert macro vt6655_mac_clear_stck_ds to function

From: Philipp Hortmann
Date: Thu Jul 28 2022 - 02:00:00 EST


Convert once used macro to static function. Multiline macros are not
liked by kernel community. Rename variable byOrgValue to reg_value to
avoid CamelCase which is not accepted by checkpatch.pl. Change variable
declaration to u8 as this improves readability.
