Subject: [PATCH 086/389] input: goodix: Don't disable regulators during
suspend
It does no harm to disable them, but on Pinephone we have other
peripherals attached to the same power supplies, whose drivers
will not reference the regulator, so powering down the regulators
from Goodix driver will break those other devices.
Until those drivers gain the regulator support, don't disable
the regulators in Goodix driver.
