Still not really agree with it... In the commit message you state that errors are not properly handled and so let's use 'devm_clk_get_optional()'. I don't think that is true because If im not missing nothing there's no fundamental change between the previous code and using 'devm_clk_get_optional()'. So to me this is an enhancement because we were doing something "by hand" when we have an API for it.
That said, introducing dev_err_probe() indeed stops possibly annoying error messages for EPROBE_DEFER (and that could be seen as a fix, not really devm_clk_get_optional()). I honestly still don't see it as fix but we are also not adding a Fixes tag so I don't really care :).
(But I still think the commit message is a bit misleading)
