From c3b2c2581988d304127c2aa218430b5fca88ce56 Mon Sep 17 00:00:00 2001 From: Tommi Rantala Date: Mon, 26 Nov 2012 04:16:44 +0000 Subject: [PATCH] irda: irttp: fix memory leak in irttp_open_tsap() error path Cleanup the memory we allocated earlier in irttp_open_tsap() when we hit this error path. The leak goes back to at least 1da177e4 ("Linux-2.6.12-rc2"). Discovered with Trinity (the syscall fuzzer). Signed-off-by: Tommi Rantala Signed-off-by: David S.
