How? I see ftbl_disp_cc_mdss_mdp_clk_src[] has multiple frequencies and
clk_rcg2_shared_ops so it doesn't look like anything in the clk driver
is preventing the frequency from changing beyond the assigned value.

This changelog should be removed.

I thought folks were saying that this is bad to keep? I don't really
mind either way, but I guess it's better to drop the fixes tag because
this is largely a performance improvement?
