6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Uwe Kleine-König u.kleine-koenig@pengutronix.de
commit a297d07b9a1e4fb8cda25a4a2363a507d294b7c9 upstream.
With args->args_count == 2 args->args[2] is not defined. Actually the flags are contained in args->args[1].
