From 19099dc393f3ca1fd9690f914e50278cf2aee78a Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 16 Dec 2016 12:35:39 +0300 Subject: scsi: dpt_i2o: double free if adpt_i2o_online_hba() fails There are two places where adpt_i2o_online_hba() is called. Both callers call adpt_i2o_delete_hba(pHba) if adpt_i2o_online_hba() fails and since we also free it here that causes a double free bug. Signed-off-by: Dan Carpenter Signed-off-by: Martin K.
