Subject: net: lan966x: remove debugfs directory in probe() error path
From: Herve Codina <herve.codina@xxxxxxxxxxx>
commit 99975ad644c7836414183fa7be4f883a4fb2bf64 upstream.
A debugfs directory entry is create early during probe(). This entry is
not removed on error path leading to some "already present" issues in
case of EPROBE_DEFER.
Create this entry later in the probe() code to avoid the need to change
many 'return' in 'goto' and add the removal in the already present error
path.
