+Subject: media: dib0700: fix invalid dvb_detach argument
+
+From: Andrey Konovalov <andreyknvl@google.com>
+
+commit eb0c19942288569e0ae492476534d5a485fb8ab4 upstream.
+
+dvb_detach(arg) calls symbol_put_addr(arg), where arg should be a pointer
+to a function. Right now a pointer to state->dib7000p_ops is passed to
+dvb_detach(), which causes a BUG() in symbol_put_addr() as discovered by
+syzkaller. Pass state->dib7000p_ops.set_wbd_ref instead.
