[ 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.
