This feels new featureish to me - it'll give you runtime PM where
previously there was none.

Apparently all patches which have a word 'fix' in commit message are
auto-selected. I agree that it's better not to port this patch.

Yeah, it's a fairly common source of false positives :/

And some of that falls on me: if it's obvious that the "fix" isn't a
real fix, I won't take it. In cases like this it's not clear to me
whether it's purely a better behaviour, or whether the devices staying
on/off/etc causes an actual problem.

You made the right choice. It's indeed not obvious from commit message
what is achieved with this change. This patch shouldn't have any visible
effect on older kernels which don't support power management in a case
of Tegra SoCs. It will have effect using the upcoming kernels, once the
full set of in-progress power management patches will be merged.
