Merge branches 'acpi-pci', 'acpi-irq' and 'acpi-assorted'
* acpi-pci: ACPI, PCI, irq: remove redundant check for null string pointer ACPI / PCI: Simplify acpi_penalize_isa_irq() ACPI, PCI, irq: remove interrupt number restriction ACPI, PCI, irq: remove interrupt count restriction * acpi-irq: ACPI / spi: attach GPIO IRQ from ACPI description to SPI device ACPI / gpio: Add irq_type when a GPIO is used as an interrupt ACPI: Rename acpi_gsi_get_irq_type to acpi_dev_get_irq_type and export symbol * acpi-assorted: ACPI / SBS: fix inconsistent indenting inside if statement ACPI: Fix build errors due objects compiled unconditionally
