[PATCH] clk: at91: pmc: Use common error handling code in pmc_register_ops()

[Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Tue, 17 Sep 2024 14:28:22 +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.
