[PATCH 6.1 027/280] ASoC: tlv320adcx140: fix null pointer

From: Emil Svendsen <emas@bang-olufsen.dk>

[ Upstream commit be7664c81d3129fc313ef62ff275fd3d33cfecd4 ]

The "snd_soc_component" in "adcx140_priv" was only used once but never
set. It was only used for reaching "dev" which is already present in
"adcx140_priv".
