Subject[PATCH 1/4] drm/msm/dsi: convert to msm_clk_get()
Date
We already have, as a result of upstreaming the gpu bindings,
msm_clk_get() which will try to get the clock both without and with a
"_clk" suffix. Use this in DSI code so we can drop the "_clk" suffix
in bindings while maintaing backwards compatibility.
