  The goto statement jump is not required at the end of the if statement
block, because it will be executed to the lower part of the goto
statement.

The patch itself is OK, but its subject should be something like "PM:
hibernate: x86: Drop unneeded goto statement from arch_resume_nosmt()"
and the changelog should be more precise, for example:

"The last goto statement in arch_resume_nosmt() is not necessary,
because the target label is right next to it."

Please update.
