Subject: KVM: ARM/arm64: fix non-const declaration of function returning const
From: Will Deacon <will.deacon@xxxxxxx>
commit 6951e48bff0b55d2a8e825a953fc1f8e3a34bf1c upstream.
Sparse kicks up about a type mismatch for kvm_target_cpu:
arch/arm64/kvm/guest.c:271:25: error: symbol 'kvm_target_cpu' redeclared with different type (originally declared at ./arch/arm64/include/asm/kvm_host.h:45) - different modifiers
so fix this by adding the missing const attribute to the function
declaration.
