From: Yangtao Li Date: Tue, 20 Jun 2023 09:07:22 +0000 (+0800) Subject: thermal/hwmon: Add error information printing for devm_thermal_add_hwmon_sysfs() X-Git-Tag: v6.6.17~4603^2^2~11 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8416ecfb3292321c55719c7c1a69dec7769bfbc1;p=platform%2Fkernel%2Flinux-rpi.git thermal/hwmon: Add error information printing for devm_thermal_add_hwmon_sysfs() Ensure that all error handling branches print error information. In this way, when this function fails, the upper-layer functions can directly return an error code without missing debugging information. Otherwise, the error message will be printed redundantly or missing.
