staging: android-alarm: Switch from wakelocks to wakeup sources In their current AOSP tree, the Android in-kernel wakelock infrastructure has been reimplemented in terms of wakeup sources: http://git.linaro.org/gitweb?p=people/jstultz/android.git;a=commitdiff;h=e9911f4efdc55af703b8b3bb8c839e6f5dd173bb The Android alarm driver currently has stubbed out calls to wakelock functionality. So this patch simply converts the stubbed out wakelock calls to wakeup source calls, and removes the empty wakelock macros Greg, would you mind queuing this in staging-next?

Kim <dae@velatum.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> staging: alarm-dev: Drop pre Android 1.0 _OLD ioctls Per Colin's comment: "The "support old userspace code" comment for those two ioctls has been there since pre-Android 1.0. Those apis are not exposed to Android apps, I don't see any problem deleting them." Thus this patch removes the ANDROID_ALARM_SET_OLD and ANDROID_ALARM_SET_AND_WAIT_OLD ioctl compatability logic.
