[PATCH 5.11 084/122] net: davicom: Fix regulator not turned off on failed probe

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

commit 31457db3750c0b0ed229d836f2609fdb8a5b790e upstream.

When the probe fails, we must disable the regulator that was previously
enabled.

This patch is a follow-up to commit ac88c531a5b3
("net: davicom: Fix regulator not turned off on failed probe") which missed
one case.

Fixes: 7994fe55a4a2 ("dm9000: Add regulator and reset support to dm9000")
