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. Fixes: 3b74c73 (usb: gadget: inode: switch over to memdup_user()) Cc: <stable@vger.kernel.org> # v3.15+ Signed-off-by: Mario Schuknecht <mario.schuknecht@dresearch-fe.de> Signed-off-by: Felipe Balbi <balbi@ti.com>
