Subject: [PATCH] ASoC: tas2783A: remove unused tas25xx_(de)register_misc() functions
Date: Tue,  9 Jun 2026 18:35:34 -0700	[thread overview]
Message-ID: <20260610013534.30762-1-enelsonmoore@gmail.com> (raw)

The tas2783 driver defines two functions tas25xx_register_misc and
tas25xx_deregister_misc which have stub implementations. It uses
external implementations if CONFIG_SND_SOC_TAS2783_UTIL is enabled, but
that symbol has never been present in the kernel. Therefore, these
functions are entirely unused. Remove them.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.
