Subject: [PATCH 3/3] remoteproc: fix various checkpatch warnings
Fix all the checkpatch warnings in the core remoteproc
code. The fixes cover the following warnings:
1. WARNING: void function return statements are not generally useful
2. WARNING: Possible unnecessary 'out of memory' message
3. WARNING: line over 80 characters
4. WARNING: braces {} are not necessary for single statement blocks
5. WARNING: Unnecessary space before function pointer arguments
