4.20-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Zijlstra <peterz@infradead.org>
commit f764c58b7faa26f5714e6907f892abc2bc0de4f8 upstream.
Guenter reported a build warning for CONFIG_CPU_SUP_INTEL=n:
> With allmodconfig-CONFIG_CPU_SUP_INTEL, this patch results in: > > In file included from arch/x86/events/amd/core.c:8:0: > arch/x86/events/amd/../perf_event.h:1036:45: warning: ‘struct cpu_hw_event’ declared inside parameter list will not be visible outside of this definition or declaration > static inline int intel_cpuc_prepare(struct cpu_hw_event *cpuc, int cpu)
While harmless (an unsed pointer is an unused pointer, no matter the type) it needs fixing.
