[PATCH 2/2] clk: qcom: gcc-sc8280xp: Don't keep display AHB clocks always-on

From: Konrad Dybcio
Date: Fri Sep 29 2023 - 09:39:32 EST


These clocks are consumed by the dispcc[01] clock controllers, so there's
no reason to keep them on from gcc probe. Remove that hack.

Fixes: d65d005f9a6c ("clk: qcom: add sc8280xp GCC driver")
