Subject: [PATCH v4 net-next 01/13] ACPI: bus: add stub acpi_dev_found() to linux/acpi.h

From: Kejian Yan <yankejian@...wei.com>

acpi_dev_found() will be used to detect if a given ACPI device is in the
system. It will be compiled in non-ACPI case, but the function is in
acpi_bus.h and acpi_bus.h can only be used in ACPI case, so this patch add
the stub function to linux/acpi.h to make compiled successfully in
non-ACPI cases.
