Subject: [PATCH 1/3] idle-monitor: Make helper function static
066919
066919
It wasn't used outside the file, so no reason to not have it static.

Subject: [PATCH 3/3] idle-monitor: Reset timeout before firing watch
066919
066919
The watch might be removed during firing, meaning the source is
066919
destroyed after returning. Avoid use-after-free by unsetting the timeout
066919
before firing. Returning G_SOURCE_CONTINUE in that case is harmless, as
066919
source is destroyed.
