Subject: [PATCH 5/7] ACPI / irq: Add GSI IRQ domain getter function
Date: Sun, 31 Mar 2019 15:35:31 +0300	[thread overview]
Message-ID: <1554035733-11827-1-git-send-email-hhhawa@amazon.com> (raw)

Add GSI IRQ domain getter function (acpi_get_gsi_domain_id), for IRQ
drivers that use ACPI and need the IRQ parent domain to register their
irq-chip device.
