I was doing the final pass before applying and I think that this is not
quite correct, as it does not handle -EPROBE_DEFER properly which is
quite common. I think we should do something like this:

		error = PTR_ERR(kp->clk);
		if (error != -ENOENT) {
			if (error != -EPROBE_DEFER)
				dev_err(.. "Failed to get clock" ...);
			return error;
		}
		dev_dbg(... "No clock specified" ...);

No need to resubmit if you are OK with this, I can make the change
locally.

Checkpach should have warned you that it should have been "} else {";
I'll fix it up locally along with few other cosmetic changes and
dropping a few extra headers.

Thanks.
