Subject: [PATCH v2 RESEND 20/23] pmcraid: Use pci_enable_msix_range() instead of pci_enable_msix()
Date: Mon, 14 Apr 2014 10:05:44 +0200	[thread overview]
Message-ID: <585bd723050f1aad76c0cc8972293768eccdfc4c.1397461652.git.agordeev@redhat.com> (raw)
In-Reply-To: <cover.1397461652.git.agordeev@redhat.com>

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.
