CVE-2021-47473

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix a memory leak in an error path of qla2x00_process_els() Commit 8c0eb596baa5 ("[SCSI] qla2xxx: Fix a memory leak in an error path of qla2x00_process_els()"), intended to change: bsg_job->request->msgcode == FC_BSG_HST_ELS_NOLOGIN bsg_job->request->msgcode != FC_BSG_RPT_ELS but changed it to: bsg_job->request->msgcode == FC_BSG_RPT_ELS instead. Change the == to a != to avoid leaking the fcport structure or freeing unallocated memory.
