Subject: [PATCH v3 1/8] pciehp: Make check_link_active() non-static
Date: Tue, 17 Dec 2013 12:05:28 -0800 [thread overview]
Message-ID: <52B0AE88.8090203@gmail.com> (raw)
check_link_active() functionality needs to be used by subsequent patches
(that introduce link state change based hotplug). Thus make the function
non-static, and rename it to pciehp_check_link_active() so as to be
consistent with other non-static functions.
