From b44be2462dbe3e23f0aedff64de52a1e8e47a1cd Mon Sep 17 00:00:00 2001 From: Mario Schuknecht Date: Tue, 16 Dec 2014 08:58:57 +0100 Subject: [PATCH] usb: gadget: gadgetfs: Free memory allocated by memdup_user() Commit 3b74c73f8d6f053f422e85fce955b61fb181cfe7 switched over to memdup_user() in ep_write() function and removed kfree (kbuf). memdup_user() function allocates memory which is never freed.
