[PATCH] arch/x86/amd: Remove set but not used variable 'active'

From: Zheng Yongjun
Date: Sun Nov 10 2019 - 04:46:50 EST


Fixes gcc '-Wunused-but-set-variable' warning:

arch/x86/events/amd/core.c: In function amd_pmu_handle_irq:
arch/x86/events/amd/core.c:656:6: warning: variable active set but not used [-Wunused-but-set-variable]

active is never used, so remove it.
