[PATCH 5.14 152/169] scsi: qla2xxx: Fix a memory leak in an error path of qla2x00_process_els()

[Greg Kroah-Hartman]

From: Joy Gu <jgu@xxxxxxxxxxxxxxx>

[ Upstream commit 7fb223d0ad801f633c78cbe42b1d1b55f5d163ad ]

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

to:

        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.
