[PATCH v3 3/7] drm/msm/dpu: drop duplicated intf/wb indices from encoder structs
Dmitry Baryshkov
dmitry.baryshkov at linaro.org
Thu Jun 1 17:22:32 UTC 2023
Remove intf_idx and wb_idx fields from struct dpu_encoder_phys and
struct dpu_enc_phys_init_params. Set the hw_intf and hw_wb directly and
use them to get the instance index.
