Subject: [PATCH v2] x86/pci: fix intel_mid_pci.c build error when ACPI is not

From: Randy Dunlap <>

Fix build error when CONFIG_ACPI is not set/enabled by adding
the header file <asm/acpi.h> which contains a stub for the function
in the build error.

../arch/x86/pci/intel_mid_pci.c: In function ‘intel_mid_pci_init’:
../arch/x86/pci/intel_mid_pci.c:303:2: error: implicit declaration of function ‘acpi_noirq_set’; did you mean ‘acpi_irq_get’? [-Werror=implicit-function-declaration]

Fixes: a912a7584ec3 ("x86/platform/intel-mid: Move PCI initialization to arch_init()")
