Add device tree for the Dell Inspiron 14 Plus 5441 laptop which uses
the Qualcomm Snapdragon X Plus X1P64100 SoC. The device shares the
same platform (Thena) as the Dell Inspiron 14 Plus 7441 and Dell
Latitude 7455, and reuses the x1-dell-thena.dtsi include.

The 5441 has 2 speakers only (no front tweeters), so the tweeter
nodes from x1-dell-thena.dtsi are deleted. There is no touchscreen.

I'm a little surprised this compiles.. but this doesn't do what you'd like
it to - it would, if the speaker@0,1 node was a child of the node bearing
the 'sound' label.

Also, I'm going to assume that the 2spk configuration follows other
machines, where only a single soundwire host is used (i.e. "left tweeter"
is actually "right speaker"), rather than the two soundwire hosts normally
used to house 2 speakers each only being utilized to drive one per side

To remove the inexistent ones, add:

/delete-node/ &right_woofer;
/delete-node/ &right_tweeter;

And re-label the existing ones:

left_spkr: &left_woofer {};
right_spkr: &left_tweeter {};

(customarily between the includes and the root node ("/ {"))

And then because these labels cease to exist, you'll need to make
adjustments to anything that references them, which I think will be
best to do as:

&wsa_playback_codec {
	sound-dai = <&left_spkr>, <&right_spkr>,
		    <&swr0 0>, <&lpass_wsamacro 0>;
};

And at last, to disable the now-unused swr3 host:

&swr3 {
	status = "disabled";
};

Please also keep a uniform \n before 'status'
