Without CONFIG_PM_SLEEP, the pm_generic_suspend() function cannot be called
since it is defined to NULL:

Arnd, thanks, but the breakage never made it to the pull request.

lkft caught it[1] and I had dropped the series from my queue[2].
Kevin reposted a v5 of the series with the fixups[3] - hopefully with
the dependencies merged, we should see that go via Ulf's tree for the
next window.
