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

[This is an automated email]

This commit has been processed because it contains a "Fixes:" tag
fixing commit: 66d0e797bf09 ("Revert "PM / devfreq: Modify the device name as devfreq(X) for sysfs"").

The fixes commit was merged to v5.6-rc4. As your test result,
it was possible to build above v5.6. It is not problem. Thanks for your testing.
