Subject[PATCH v7 02/10] staging: fsl-mc: fix macros with possible side effects
Date
From: Laurentiu Tudor <laurentiu.tudor@nxp.com>

Several macros were triggering this checkpatch.pl warning:
"Macro argument reuse '$arg' - possible side-effects?"
Fix the warning by avoiding multiple macro argument use.

Signed-off-by: Laurentiu Tudor <laurentiu.tudor@nxp.com>
