* Due to HW bug, LAN8700 sometimes does not detect presence of energy in the

LAN87xx family of PHY chips.
* The lan87xx_read_status() was improved to acquire ENERGYON bit. Its previous
algorythm still not reliable on 100 % and sometimes skip cable plugging.

Is there a reason to move this declaration?
There is no strict requirement to move declaration of the rc.
It was made just to have all declarations easily visible.
Generally it's better to have declarations
in the minimal/narrowest scope possible.
Agreed, and it's %100 unrelated to the purpose of this patch so not
should be included for that reason as well.
You will need to respin this patch with the variable moving elided.
