We set rtlhal->last_suspend_sec to an uninitialized stack variable, but unfortunately gcc never warned about this, I only found it while working on another patch. I opened a gcc bug for this.
Presumably the value of rtlhal->last_suspend_sec is not all that important, but it does get used, so we probably want the patch backported to stable kernels.
