[PATCH] riscv: kvm: define vcpu_sbi_ext_pmu in header

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Sparse is giving a warning about vcpu_sbi_ext_pmu not being
defined, so add a definition to the relevant header to fix
the following:

arch/riscv/kvm/vcpu_sbi_pmu.c:81:37: warning: symbol 'vcpu_sbi_ext_pmu' was not declared. Should it be static?

Fixes: 3e5e56c60a1477 ("riscv: kvm: move extern sbi_ext declarations to a header")
