Subject: [PATCH 5.15 080/132] net: systemport: Fix an error handling path in bcm_sysport_probe()

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

[ Upstream commit ef6b1cd11962aec21c58d137006ab122dbc8d6fd ]

if devm_clk_get_optional() fails, we still need to go through the error
handling path.

Add the missing goto.
