From: Arnd Bergmann arnd@arndb.de

commit 3f2a162fab15aee243178b5308bb5d1206fc4043 upstream.

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.
