Subject: [PATCH 4/7] KVM: arm64: Remove useless local variable
Date: Fri, 24 Jul 2020 15:35:03 +0100 [thread overview]
Message-ID: <20200724143506.17772-5-will@kernel.org> (raw)
In-Reply-To: <20200724143506.17772-1-will@kernel.org>
'is_iabt' is used exactly once in kvm_handle_guest_abort(). Remove it,
and inlined its definition instead.
