| |
From: Arnd Bergmann <arnd@arndb.de>
When CONFIG_HW_PERF_EVENTS is disabled, the hardware lockup detector fails to link:
ld.lld: error: undefined symbol: hw_nmi_get_sample_period >>> referenced by watchdog_hld.c >>> watchdog_hld.o:(hardlockup_detector_event_create) in archive kernel/built-in.a
Fix the dependency to refer to the Kconfig symbol that actually controls the feature.
