[v10,04/18] drm: exynos: dsi: Switch to devm_drm_of_dsi_get_bridge

Commit Message

Jagan Teki Dec. 14, 2022, 12:58 p.m. UTC

devm_drm_of_dsi_get_bridge is capable of looking up the downstream
DSI bridge and panel and trying to add a panel bridge if the panel
is found.

Replace explicit finding calls with devm_drm_of_dsi_get_bridge.
