Subject: [PATCH] regulator: qcom-rpmh: Implement get_optimum_mode(), not set_load()
Date:   Tue, 26 Jul 2022 10:20:29 -0700
Message-Id: <20220726102024.1.Icc838fe7bf0ef54a014ab2fee8af311654f5342a@changeid>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Since we don't actually pass the load to the firmware, switch to using
get_optimum_mode() instead of open-coding it.

This is intended to have no effect other than cleanup.
