Subject: [PATCH 5.14 074/162] platform/x86: dell: fix DELL_WMI_PRIVACY dependencies & build error

From: Randy Dunlap <rdunlap@...radead.org>

[ Upstream commit 5b72dafaca73b33416c82457ae615e6f2022e901 ]

When DELL_WMI=y, DELL_WMI_PRIVACY=y, and LEDS_TRIGGER_AUDIO=m, there
is a linker error since the LEDS trigger code is built as a loadable
module. This happens because DELL_WMI_PRIVACY is a bool that depends
on a tristate (LEDS_TRIGGER_AUDIO=m), which can be dangerous.

ld: drivers/platform/x86/dell/dell-wmi-privacy.o: in function `dell_privacy_wmi_probe':
dell-wmi-privacy.c:(.text+0x3df): undefined reference to `ledtrig_audio_get'

Fixes: 8af9fa37b8a3 ("platform/x86: dell-privacy: Add support for Dell hardware privacy")
