From 7363cfc8666692a5263c646e68e54900b536cd7e Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Mon, 29 May 2006 23:28:05 -0400 Subject: Input: sidewinder - fix memory leak In sw_connect we leak 'buf' and 'idbuf' when we do not leave via one of the fail* labels. This was spotted by the coverity checker. Patch is compile tested only due to lack of hardware.
