[PATCH 1/5][v2] staging: fsl-mc: fix several checkpath.pl warnings

From: laurentiu.tudor
Date: Mon May 22 2017 - 08:10:05 EST

From: Laurentiu Tudor <laurentiu.tudor@xxxxxxx>

Remove several unneeded #includes, forward
declarations and fix several issues reported
by checkpatch.pl --strict, such as:
- kfree(NULL) is safe and check is not required
- macro argument reuse may cause possible side effects
- enclose macro params in parens to avoid precedence issues
- coding style

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

Notes:
-v2
