Subject: [PATCH 1/2] soc: qcom: rpmhpd: Use corner in power_off
Date: Fri, 2 Jul 2021 17:54:15 -0700 [thread overview]
Message-ID: <20210703005416.2668319-2-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20210703005416.2668319-1-bjorn.andersson@linaro.org>
rpmhpd_aggregate_corner() takes a corner as parameter, but in
rpmhpd_power_off() the code requests the level of the first corner
instead.
In all (known) current cases the first corner has level 0, so this
change should be a nop, but in case that there's a power domain with a
non-zero lowest level this makes sure that rpmhpd_power_off() actually
requests the lowest level - which is the closest to "power off" we can
get.
While touching the code, also skip the unnecessary zero-initialization
of "ret".
