[PATCH 4.9 116/251] scsi: hpsa: Fix possible memory leak in hpsa_add_sas_device()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Yang Yingliang <yangyingliang@xxxxxxxxxx>

[ 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.

Fixes: d04e62b9d63a ("hpsa: add in sas transport class")
