Drivers: hv: rename sc_lock to the more generic lock
sc_lock spinlock in struct vmbus_channel is being used to not only protect the sc_list field, e.g. vmbus_open() function uses it to implement test-and-set access to the state field. Rename it to the more generic 'lock' and add the description. Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Signed-off-by: K. Y. Srinivasan <kys@microsoft.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
