Subject: cpufreq: qcom-cpufreq-hw: Use dev_err_probe() when failing to get icc paths
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5ee64250286e8c5162808667a9a8668488d9f577;p=linux.git

cpufreq: qcom-cpufreq-hw: Use dev_err_probe() when failing to get icc paths

This way, if there's an issue (in this case a -EPROBE_DEFER), you can
get useful output:

    [root@dhcp19-243-150 ~]# cat /sys/kernel/debug/devices_deferred
    18591000.cpufreq        qcom-cpufreq-hw: Failed to find icc paths
