From 30d3df41b32b1ea63d3ebc52ef5644cbe41520f4 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 25 Nov 2010 00:06:55 +0100 Subject: ACPI / PM: Introduce function for refcounting device power resources Introduce function acpi_power_on_resources() that reference counts and possibly turns on ACPI power resources for a given device and a given power state of it. This function will be used for reference counting device power resources during initialization. Signed-off-by: Rafael J.
