[PATCH] staging: dgnc: Replace macro with flow control statement by a function

[Arjun Krishna Babu <arjunkrishnababu96@gmail.com>]

This patch fixes the checkpatch.pl warning:

WARNING: Macros with flow control statements should be avoided

Replace the macro with a function doing the exact same task as the
macro.
