[PATCH v7 14/19] PM / devfreq: tegra30: Don't enable already enabled consecutive interrupts

From: Dmitry Osipenko
Date: Tue Oct 29 2019 - 18:07:01 EST


Consecutive up/down interrupt-bit is set in the interrupt status register
only if that interrupt was previously enabled. Thus enabling the already
enabled interrupt doesn't do much for us.
