Subject: [PATCH 1/5][v2] staging: fsl-mc: fix several checkpath.pl warnings
From: Laurentiu Tudor <laurentiu.tudor@....com>
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@....com>
