Subject: [PATCH 6/7] KVM: arm64: Change return type of kvm_vm_ioctl_mte_copy_tags() to "int"
Date:   Fri,  3 Feb 2023 10:42:29 +0100
Message-Id: <20230203094230.266952-7-thuth@redhat.com>
In-Reply-To: <20230203094230.266952-1-thuth@redhat.com>
References: <20230203094230.266952-1-thuth@redhat.com>

Precedence: bulk

This function only returns normal integer values, so there is
no need to declare its return value as "long".
