Subject: [PATCH 1/2] devfreq: Rename devfreq_update_status() to devfreq_update_stats() and viceversa
devfreq has two functions with very similar names, devfreq_update_status()
and devfreq_update_stats(). _update_status() currently updates
frequency transitions statistics, while _update_stats() retrieves the
device 'status'. The function names are inversed with respect to what
the functions are actually doing, rename devfreq_update_status() to
devfreq_update_stats() and viceversa.
Signed-off-by: Matthias Kaehlcke <mka@...omium.org>
---
We could also rename the current devfreq_update_stats() to
devfreq_refresh_status() to make it easier to distinguish it from
devfreq_update_stats().
