[PATCH v3 1/2] ASoC: ak4642: Minor cleanups in probe()

From: Biju Das
Date: Thu Aug 31 2023 - 16:47:48 EST


Some minor cleanups:
Replace local variable np with dev_fwnode()
Replace dev_err()->dev_err_probe().
Remove comma in the terminator entry for OF table.
Drop a space in the terminator entry for ID table.
