[PATCH v2 00/23] scsi: Use pci_enable_msix_range() instead of pci_enable_msix()

[Alexander Gordeev <agordeev@redhat.com>]

Hello!

This series is against James Bottomley's SCSI tree [1], but it needs
commit f7fc32c ("PCI/MSI: Add pci_enable_msi_exact() and
pci_enable_msix_exact()") from from Bjorn Helgaas's PCI tree [2]:

1. git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git for-next
2. git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git pci/msi

Recently pci_enable_msix_exact() function has been accepted to
the mainline. That is a variation of pci_enable_msix_range() which
allows a device driver to request a particular number of MSI-Xs.

As result, most of the changes posted in version 1 of this series
are invalidated and need to use pci_enable_msix_exact() instead of
originally posted pci_enable_msix_range() usages.

I removed almost all ACKs, since unlike pci_enable_msix_range()
function which returns the number of MSI-Xs allocated or negative
errno, pci_enable_msix_exact() returns either zero success code or
a negative errno. Although this change is simple, it still entails
an updated error code analysis and would be better reviewed by
driver maintainers.

Thanks!
