From 2b8e6b58889c672e1ae3601d9b2b070be4dc2fbc Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Sun, 13 Apr 2025 11:11:42 +0100 Subject: [PATCH] cpufreq: cppc: Fix invalid return value in .get() callback Returning a negative error code in a function with an unsigned return type is a pretty bad idea. It is probably worse when the justification for the change is "our static analisys tool found it".
