[PATCH 5.15 064/135] net: mdio: Fix ENOMEM return value in BCM6368 mux bus controller

[Greg Kroah-Hartman]

From: Niels Dossche <dossche.niels@xxxxxxxxx>

commit e87f66b38e66dffdec9daa9f8f0eb044e9a62e3b upstream.

Error values inside the probe function must be < 0. The ENOMEM return
value has the wrong sign: it is positive instead of negative.
Add a minus sign.
