I fixed coding style issue which was there. Some of them are false positive.
I don't want to disturb people with next big pack and next version that's why I
updated only branch on git (Patches has name microblaze_v8-pre)
Below is part of log with faults which are announcing with checkpatch.pl script
+ my comments. I remove patches without any fault.

Thanks for noticing me in cases where I am wrong.

Thanks,
Michal
