This is version 2 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. V1:

   - Introduce retain_ptr() to allow using __free() when the allocation is
     consumed by a called function (on success) and therefore no_free_ptr()
     can't be used.

   - Rework the PCI/MSI changes to avoid gotos in guard sections

   - Drop patch 1 as it's already applied

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

Patches 3,4,6-10 are unmodifed.

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
