From fda34a5d304d0b98cc967e8763b52221b66dc202 Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Fri, 11 Nov 2022 12:30:12 +0800 Subject: [PATCH] scsi: hpsa: Fix possible memory leak in hpsa_add_sas_device() If hpsa_sas_port_add_rphy() returns an error, the 'rphy' allocated in sas_end_device_alloc() needs to be freed. Address this by calling sas_rphy_free() in the error path.
