Subject: Re: [PATCH v3 1/6] tpm: drop 'iobase' from struct tpm_vendor_specific
Date: Thu, 31 Mar 2016 12:48:17 +0300	[thread overview]
Message-ID: <20160331094817.GA12189@intel.com> (raw)
In-Reply-To: <CALD+uuxRKmGHoNcyOv7kSTVccFpmi6AzKxecHWPFcER=VR1zhA-JsoAwUIsXosN+BqQ9rBEUg@public.gmane.org>

This and 3/6 had minor style issues.

If there are nothing biggger in the patch I guess I adjust the patches
myself. I'll still hold for other comments (maybe from Jason) and test
the patches.

If there are bigger reasons to fix the series then you could fix also
style issues.
