Subject: scsi: qla2xxx: Remove unsupported ql2xenabledif option
From: Manish Rangankar <mrangankar@xxxxxxxxxxx>
commit e9105c4b7a9208a21a9bda133707624f12ddabc2 upstream.
User accidently passed module parameter ql2xenabledif=1 which is
unsupported. However, driver still initialized which lead to guard tag
errors during device discovery.
Remove unsupported ql2xenabledif=1 option and validate the user input.
