Subject: [PATCH] sound: hda: tas2781: mark const variables as __maybe_unused
From: Arnd Bergmann <arnd@...db.de>
An earlier patch changed the DECLARE_TLV_DB_SCALE declaration, but
now there are additional static const variables that cause
the same build warnings:

20 | static const DECLARE_TLV_DB_SCALE(tas2563_dvc_tlv, -12150, 50, 1);
| ^~~~~~~~~~~~~~~
Mark them all as unused as well.
