Subject: [PATCH v2 9/9] wil6210: Use pci_enable_msi_range()
Date: Fri, 17 Jan 2014 17:02:23 +0100 [thread overview]
Message-ID: <aedc9b7eb82232204a7d65b4c7d3302ba6ba3892.1389904167.git.agordeev@redhat.com> (raw)
In-Reply-To: <cover.1389904166.git.agordeev@redhat.com>
As result 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() and pci_enable_msix_range()
interfaces.
