[PATCH] macintosh: Use common error handling code in via_pmu_led_init()

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Thu, 3 Oct 2024 21:06:42 +0200

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

This issue was detected by using the Coccinelle software.
