The 'also' sounds like the patch is fixing 2 issues, but it is just fixing one.
Will update the commit message in next revision.

would hang if num-ees was not zero, which occurs when the SoCs power on

The offending commit is just in the -next branch. So CCing stable is pointless.
Ok, will remove in next revision.
