[PATCH] Bluetooth: btmtk: hide unused btmtk_mt6639_devs[] array
From: Arnd Bergmann
Date: Thu Apr 02 2026 - 10:18:32 EST
From: Arnd Bergmann <arnd@xxxxxxxx>
When USB support is disabled, the array is not referenced anywhere,
causing a warning:
drivers/bluetooth/btmtk.c:35:3: error: 'btmtk_mt6639_devs' defined but not used [-Werror=unused-const-variable=]
35 | } btmtk_mt6639_devs[] = {
| ^~~~~~~~~~~~~~~~~
Move it into the #ifdef block.
Fixes: 4cdd001ff03f ("Bluetooth: btmtk: Add MT6639 (MT7927) Bluetooth support")
