Subject: [PATCH] clk: mediatek: clk-mt8173-apmixedsys: Use common error
 handling code in clk_mt8173_apmixed_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 26 Feb 2024 13:10:37 +0100

Add a label so that a bit of exception handling can be better reused
at the end of this function implementation.
