Merge tag 'acpi-6.19-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI support fix from Rafael Wysocki:
"This fixes the ACPI/PCI legacy interrupts (INTx) parsing in the case
when the ACPI Global System Interrupt (GSI) value is a 32-bit one with
the MSB set.
That was interpreted as a negative integer and caused
acpi_pci_link_allocate_irq() to fail and acpi_irq_get_penalty() to
trigger an out-of-bounds array dereference (Lorenzo Pieralisi)"
