From dafd6c496381c1cd1f5ba9ad953e810bdcc931bc Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Tue, 27 Mar 2018 14:26:01 +0100 Subject: [PATCH] libata: ensure host is free'd on error exit paths The host structure is not being kfree'd on two error exit paths leading to memory leaks. Add in new err_free label and kfree host.
