Sigh, what you have not fixed in your patches are the basic stylistic 
mistakes I pointed out to the past:

   https://lkml.org/lkml/2013/5/1/78

(my previous feedback is also quoted below.)

Here checkpatch.pl says this about your series:

  total: 6 errors, 10 warnings, 662 lines checked

and a handful of those checkpatch.pl complaints are for valid, real 
problems.

Furthermore, you have not replied to any of those two mails of mine, nor 
have you fixed the stylistic problems I pointed out, in these latest 
patches!

To fix it simply follow the advice I gave you twice before: run 
scripts/checkpatch.pl against your patches and address any valid 
complaints it gives _BEFORE YOU RESUBMIT THEM_!

Andi, what the heck is going on here? Your behavior makes no sense to me. 
You are pretty much the only contributor I know who makes a habit out of 
willfully ignoring maintainer feedback...

Thanks,

	Ingo
