[PATCH] lpfc: fix double free on mp

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

 



From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The error path when the call to lpfc_sli_issue_mbox returns
MBX_NOT_FINISHED results in the code freeing mp and calling
lpfc_mbuf_free twice.   Fix this by jumping to the correct
part of the error clean up path.
