Subject: [PATCH] ASoC: tas2781: mark dvc_tlv with __maybe_unused
Date: Thu, 28 Mar 2024 23:47:37 +0100
Message-ID: <0e461545a2a6e9b6152985143e50526322e5f76b.1711665731.git.soyer@irl.hu>

Since we put dvc_tlv static variable to a header file it's copied to
each module that includes the header. But not all of them are actually
used it.

Fix this W=1 build warning:

include/sound/tas2781-tlv.h:18:35: warning: 'dvc_tlv' defined but not
used [-Wunused-const-variable=]

Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202403290354.v0StnRpc-lkp@intel.com/
