[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: John Keeping <john@xxxxxxxxxxxx>

[ Upstream commit 38355b2a44776c25b0f2ad466e8c51bb805b3032 ]

When binding a gadget to a device, "name" is stored in gi->udc_name, but
this does not happen when unregistering and the string is leaked.
