I see there's a bunch of these already, but I think we can do better
here than dev_err_probe. We have _optional variants for the case not
getting a resource is not an error. So the called functions like
devm_clk_get can print an error. We already have this for
platform_get_irq along with a coccinelle script to fix cases. I have a
WIP branch[1] doing this.
