   4 Subject: usb: gadget: net2272: Fix a memory leak in an error handling path in 'net2272_plat_probe()'
   5
   6 From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

   8 commit ccaef7e6e354fb65758eaddd3eae8065a8b3e295 upstream.
   9
  10 'dev' is allocated in 'net2272_probe_init()'. It must be freed in the error
  11 handling path, as already done in the remove function (i.e.
  12 'net2272_plat_remove()')

  14 Fixes: 90fccb529d24 ("usb: gadget: Gadget directory cleanup - group UDC drivers")
