Subject: [PATCH] drm/msm/dpu: make dpu_hw_ctl_clear_all_blendstages clear necessary LMs
Date: Mon, 5 Jul 2021 02:05:19 +0300 [thread overview]
Message-ID: <20210704230519.4081467-1-dmitry.baryshkov@linaro.org> (raw)
dpu_hw_ctl_clear_all_blendstages() clears settings for the few first LMs
instead of mixers actually used for the CTL. Change it to clear
necessary data, using provided mixer ids.
Fixes: 25fdd5933e4c ("drm/msm: Add SDM845 DPU support")
