From 16d3659fcda922a31873e9e827b12c825b36fd11 Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Tue, 28 Oct 2008 00:14:38 +0200 Subject: [PATCH] Staging: w35und: plug memory leak in wbsoft_tx() There's no reason to duplicate the skb in wbsoft_tx() and leak GFP_ATOMIC memory as the contents are copied to ->TxBuffer in MdxTx() anyway before MLMESendFrame() returns.
