This is a note to let you know that I've just added the patch titled scsi: hpsa: Fix possible memory leak in hpsa_add_sas_device() to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: scsi-hpsa-fix-possible-memory-leak-in-hpsa_add_sas_d.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 87c175a5d31f10dc384d65c3115fab081791a642 Author: Yang Yingliang <yangyingliang@xxxxxxxxxx> Date: Fri Nov 11 12:30:12 2022 +0800 scsi: hpsa: Fix possible memory leak in hpsa_add_sas_device() [ Upstream commit fda34a5d304d0b98cc967e8763b52221b66dc202 ] 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.
