Acked-by: Anil Gurumurthy -----Original Message----- From: linux-scsi-owner@vger.kernel.org [mailto:linux-scsi-owner@vger.kernel.org] On Behalf Of Alexander Gordeev Sent: 14 April 2014 13:35 To: linux-kernel Cc: Alexander Gordeev; Anil Gurumurthy; Vijaya Mohan Guvva; linux-scsi; linux-pci Subject: [PATCH v2 RESEND 04/23] bfa: Use pci_enable_msix_exact() instead of pci_enable_msix() As result of deprecation of MSI-X/MSI enablement functions pci_enable_msix() and pci_enable_msi_block() all drivers using these two interfaces need to be updated to use the new pci_enable_msi_range() or pci_enable_msi_exact() and pci_enable_msix_range() or pci_enable_msix_exact() interfaces.
