Subject: [PATCH] scsi: lpfc: correct size for cmdwqe/rspwqe for memset

The cmdwqe and rspwqe are of type lpfc_wqe128. They should be memset
with the same type.

Fixes: 61910d6a5243 ("scsi: lpfc: SLI path split: Refactor CT paths")

Hi,

maybe even:
memset(cmdwqe, 0, sizeof(*cmdwqe));

Same below and in your other patch.

just my 2c,

Hi Muhammad,

Agreed with Christophe's comment.

memset(cmdwqe, 0, sizeof(*cmdwqe));
memset(rspwqe, 0, sizeof(*rspwqe));

Thanks,
Justin
