From d288e47c471e1090e80c62ad95882fafbf3f499d Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Wed, 19 Mar 2008 22:37:42 +0100 Subject: PM: Make wakeup flags available whenever CONFIG_PM is set The various wakeup flags and their accessor macros in struct dev_pm_info should be available whenever CONFIG_PM is enabled, not just when CONFIG_PM_SLEEP is on. Otherwise remote wakeup won't always be configurable for runtime power management. This patch (as1056b) fixes the oversight. David Brownell adds: More accurately, fixes the "regression" ... as noted sometime last summer, after 296699de6bdc717189a331ab6bbe90e05c94db06 introduced CONFIG_SUSPEND. But that didn't make the regression list for that kernel, ergo the delay in fixing it. [rjw: rebased] Signed-off-by: Alan Stern Signed-off-by: Rafael J.
