Subject: [patch V3 00/10] genirq/msi: Spring cleaning

This is version 3 of the cleanup work. The previous version can be found
here:

   https://lore.kernel.org/all/20250313130212.450198939@linutronix.de

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. V2:

   - Use __free() in __msix_setup_interrupts() - PeterZ

   - Fix a typo in the msi core code

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

Patches 1, 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
