alarmtimer: Export symbols of functions declared in linux/alarmtimer.h
Export symbols so they can be used by drivers/staging/android/alarm-dev.c if it is built as a module. So far alarm-dev is built-in but module support is planned (see drivers/staging/android/TODO). Signed-off-by: Marcus Gelderie <redmnic@gmail.com> [jstultz: tweaked commit message, also export newly added functions] Signed-off-by: John Stultz <john.stultz@linaro.org>
