Should PSU monitor be requesting and releasing GPIO on every read?

[bjwyman]

During a review to remove some excessive tracing, it was pointed out that the new power supply monitor is requesting and releasing the GPIO line on every "poll".

It is not 100% clear if this is good or bad behavior.

Should the release of the line be removed?

I don't have much of an opinion. It's not terribly different to open/read/close of the sysfs attribute. Do whatever is less of a headache in the code unless we're having performance issues.
