[PATCH 2/2] ASoC: soc-dapm.c: tidyup snd_soc_dai_link_event_pre_pmu()

[Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>]

From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

snd_soc_dai_link_event_pre_pmu() is using if/else for config->formats
check, but "else" case is for just error.
Unnecessary if/else is not good for readable code. this patch checks
if config->formats was zero as error case.

Moreover, we don't need to indicate config->formats value in error message,
because it is zero. This patch tidyup it, too.

=>	if (config->formats) {
		...
	} else {
		dev_warn(w->dapm->dev, "ASoC: Invalid format %llx specified\n",
=>			 config->formats);
		...
	}
