Is this the kind of errors I should expect in such situation?

ti-sci-clk 44043000.system-controller:clock-controller: recalc-rate failed for dev=13, clk=7, ret=-19

If this is the case, I feel like this patch should be back-ported to
stable kernels.

Any malfunction because of these errors or just some noise in the logs?
