Subject: [PATCH] acpi: fix acpi/video.h error and warning when PM is not

From: Randy Dunlap <>

When CONFIG_PM is not enabled, acpi/video.h causes a build error.
Also fix a longstanding warning.

include/acpi/video.h:22: warning: 'struct acpi_device' declared inside parameter list
include/acpi/video.h:22: warning: its scope is only this definition or declaration, which is probably not what you want
include/acpi/video.h: In function 'acpi_video_get_edid':
include/acpi/video.h:24: error: 'ENODEV' undeclared (first use in this function)
