[PATCH 3/3] drm/msm/dsi: Drop dev_pm_opp_set_rate(0)

From: Konrad Dybcio

Date: Tue Jul 28 2026 - 09:22:35 EST


From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>

dev_pm_opp_set_rate(0) removes the vote specified in required-opps but
does not actually park the clock, making it run without the necessary
power backing. Drop the explicit call to it.

Every call site of ops->link_clk_disable() is followed by
pm_runtime_put(), so the power vote will be rescinded if deemed safe.

Fixes: 32d3e0feccfe ("drm/msm: dsi: Use OPP API to set clk/perf state")
