Subject: [PATCH] PM / devfrq: Fix indentaion of devfreq_summary debugfs node
The commit 66d0e797bf09 ("Revert "PM / devfreq: Modify the device name
as devfreq(X) for sysfs"") roll back the device name from 'devfreqX'
to device name explained in DT. After applied commit 66d0e797bf09,
the indentation of devfreq_summary debugfs node was broken.
So, fix indentaion of devfreq_summary debugfs node as following:
For example on Exynos5422-based Odroid-XU3 board,
$ cat /sys/kernel/debug/devfreq/devfreq_summary
dev parent_dev governor polling_ms cur_freq_Hz min_freq_Hz max_freq_Hz
