[PATCH v1 3/4] ASoC: Intel: bytcr_rt5640: use devm_clk_get_optional() for mclk

[Andy Shevchenko]

The devm_clk_get_optional() helper returns NULL when devm_clk_get()
returns -ENOENT. This makes things slightly cleaner. The added benefit
is mostly cosmetic.

[PATCH v1 4/4] ASoC: Intel: bytcr_rt5640: Utilize dev_err_probe() to avoid log saturation

[Andy Shevchenko]

dev_err_probe() avoids printing into log when the deferred probe is invoked.
This is possible when clock provider is pending to appear.

And code that does

	if (foo) {
		[code...]
	} else {
		log_msg();
		return -ERR;
	}

should generally have its test reversed and use an unindented block.

	if (!foo) {
		log_msg();
		return -ERR;
	}
	[code...];

Yeah, sorry for that, it wasn't deliberate. I forgot to run `git msg-filter`
on these three patches to add it.

Mark, do you want me resend entire bunch(es) or just starting from these

If you're adding a commit message with automation it's probably not
adding any value.

same comment as for rt5651, I don't see the point of removing the test
