[PATCH 6.1 238/379] ASoC: ams-delta.c: use component after check

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

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

[ Upstream commit bd0f7498bc9084d8cccc5484cd004b40f314b763 ]

	static void cx81801_close()
	{
		...
(A)		struct snd_soc_dapm_context *dapm = &component->card->dapm;
		...
(B)		if (!component)
			return;
	}

(A) uses component before NULL check (B). This patch moves it after (B).
