SubjectRe: [PATCH 20/22] qla2xxx: Use pci_enable_msix_range()
Date
Looks good to me.

Acked-by: Saurav Kashyap <saurav.kashyap@qlogic.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() and pci_enable_msix_range()
>interfaces.
>
>Log message code 0x00c6 preserved, although it is reported
>after successful call to pci_enable_msix_range(), not before
>possibly unsuccessful call to pci_enable_msix(). Consumers
>of the error code should not notice the difference.
