From d6e2be988d5146d1faa8df895cd8b32106d987bd Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 5 Jan 2009 23:11:26 -0600 Subject: [PATCH] rtl8187: Fix module so that rmmod/insmod does not error Due to misunderstanding of the returned values allowed for the tx callback of mac80211, rtl8187 was using skb's that had been freed. This problem was triggered when the module was sujected to a rmmod/insmod cycle. After that was fixed, the modules would not work after the rmmod/insmod cycle until the USB device was reset.
