[PATCH 5.12 210/677] staging: qlge: fix an error code in probe()

From: Greg Kroah-Hartman
Date: Wed May 12 2021 - 14:31:55 EST


From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ Upstream commit f7bff017741d98567265ed6a6449311a51810fb6 ]

If alloc_etherdev_mq() fails then return -ENOMEM instead of success.
The "err = 0;" triggers an unused assignment now so remove that as
well.

Fixes: 953b94009377 ("staging: qlge: Initialize devlink health dump framework")
