From e98e3d712023859af7cd78bb7fdb87ea3a9ffb83 Mon Sep 17 00:00:00 2001 From: Triet Hoang Date: Fri, 18 Sep 2026 11:41:30 +0700 Subject: [PATCH] clk: raspberrypi: Handle cpufreq device registration failure Check the return value of platform_device_register_data() when registering the raspberrypi-cpufreq device and propagate the error if registration fails. This prevents the clock driver from reporting a successful probe when the cpufreq device could not be registered.
