s/even it/even when it/

Might also be a good idea to use a different subject prefix because I
was almost not going to look at the other patch, taking this to be a
replacement for it.

Although, looking at the log we have used this same prefix for both
drivers in the past...

Either of those two labels is now no longer needed. Of course it'll now
be odd to jump to fail_pm_get_sync on pinctrl_pm_select_default_state()
failure, but that's one of the reasons why label should have names
describing what they do rather than describe the failure location. I
guess we can live with that for now. I'll make a note to send a cleanup
patch for that later on.

With the fixup in the commit message and either of the labels removed:
