ion: Do not 'put' ION handle until after its final use pass_to_user() eventually calls kref_put() on an ION handle which is still live, potentially allowing for it to be legitimately freed by the client. Prevent this from happening before its final use in both ION_IOC_ALLOC and ION_IOC_IMPORT. Signed-off-by: Lee Jones <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
