Subject: [PATCHv5 1/5] pci: Export pci device config accessors
Date: Fri,  3 Feb 2017 12:55:51 -0500	[thread overview]
Message-ID: <1486144555-5526-2-git-send-email-keith.busch@intel.com> (raw)
In-Reply-To: <1486144555-5526-1-git-send-email-keith.busch@intel.com>

This patch removes the inline pci device config read and write accessors
with exported functions. This is preparing for these functions to make
use of private data.
