From 720f3d7cb19eb27f85f72836c8f8004ccb257f39 Mon Sep 17 00:00:00 2001 From: "tom.leiming@gmail.com" Date: Sun, 29 Apr 2012 22:51:02 +0000 Subject: [PATCH] usbnet: fix leak of transfer buffer of dev->interrupt The transfer buffer of dev->interrupt is allocated in .probe path, but not freed in .disconnet path, so mark the interrupt URB as URB_FREE_BUFFER to free the buffer when the URB is destroyed.
