Wysocki" Date: Wed, 24 Feb 2016 13:53:46 +0100 Subject: [PATCH] Revert "ACPI / PCI: Simplify acpi_penalize_isa_irq()" Revert commit 0971686954f9 "ACPI / PCI: Simplify acpi_penalize_isa_irq()" that depends on commit b5bd02695471 (ACPI, PCI, irq: remove interrupt count restriction) which introduced a regression and needs to be reverted for this reason.
