Re: [PATCH v4 3/4] x86/irq: Fall back to irq_chip_retrigger_hierarchy() in msi_set_affinity()
From: sashiko-bot@kernel.org

Also in:
linux-pci
msi_set_affinity() re-injects a pending interrupt on its new target by looking at the outermost domain chip and invoking its irq_retrigger() callback directly, without checking whether that callback is present. Keep calling the outermost chip's irq_retrigger() when it is present, but fall back to irq_chip_retrigger_hierarchy() otherwise, which walks up the interrupt hierarchy until it finds a chip that implements irq_retrigger().
