This is version 4 of the cleanup work. The previous version can be found
here:

While converting the MSI descriptor locking to a lock guard() I stumbled
over various abuse of MSI descriptors (again).

The following series cleans up the offending code and converts the MSI
descriptor locking over to lock guards.

Changes vs. V3:

   - Cast retain_ptr() to void so it can't be used instead of return_ptr()
     - James

   - Split up the PCI/MSI changes

   - Move setting of pci_dev::msi_enabled to the success path

   - Fix a logic inversion in the UFS change and use a cleanup function to
     simplify the error path - James

   - Collect Reviewed/Tested/Acked-by tags where appropriate

The series applies on:

    git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq/msi

and is available from git:

    git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git irq/msi

Thanks,

	tglx
