Both Sleep (where device will remain powered-on) and Deep-sleep (where
device will be powered-down are handled gracefully. Persistance sessions
are not supported across deep-sleep.

This is too big for stable; is a simpler fix possible?


Besides size, I'd also question whether this is a bug fix or a feature.
From Documentation/stable_kernel_rules.txt:
 - It must fix a problem that causes a build error (but not for things
   marked CONFIG_BROKEN), an oops, a hang, data corruption, a real
   security issue, or some "oh, that's not good" issue.  In short,
something critical.

On top of that - does it apply cleanly && has it been tested with -stable kernels?

Regards,
Horia
