[PATCH AUTOSEL 5.14 12/99] scsi: lpfc: Fix memory leaks in error paths while issuing ELS RDF/SCR request

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

 



From: James Smart <jsmart2021@xxxxxxxxx>

[ Upstream commit cd6047e92c6a5b0a44479cf98f76aac56ddfe108 ]

The ELS job request structure, that is allocated while issuing ELS RDF/SCR
request path, is not being released in an error path causing a memory leak
message on driver unload.

Free the ELS job structure in the error paths.
