Subject: [PATCH v9 09/22] powerpc/powernv: Make pnv_ioda_deconfigure_pe() visible
Date: Tue, 3 May 2016 23:22:40 +1000 [thread overview]
Message-ID: <1462281773-26438-10-git-send-email-gwshan@linux.vnet.ibm.com> (raw)
In-Reply-To: <1462281773-26438-1-git-send-email-gwshan@linux.vnet.ibm.com>
pnv_ioda_deconfigure_pe() is visible only when CONFIG_PCI_IOV is
enabled. The function will be used to tear down PE's associated
mapping in PCI hotplug path that doesn't depend on CONFIG_PCI_IOV.
This makes pnv_ioda_deconfigure_pe() visible and not depend on
CONFIG_PCI_IOV.
