From 791f97758e223de3290592d169f8e6339c281714 Mon Sep 17 00:00:00 2001 From: Li Qiang Date: Tue, 8 Nov 2016 04:11:10 -0800 Subject: [PATCH] usb: ehci: fix memory leak in ehci_init_transfer In ehci_init_transfer function, if the 'cpage' is bigger than 4, it doesn't free the 'p->sgl' once allocated previously thus leading a memory leak issue. This patch avoid this.
