Subject: Re: [PATCH net-next v1 2/3] net: phy: add API for LEDs controlled by
 ethernet PHY chips

Hi!

> Many an ethernet PHY supports various HW control modes for LEDs
> connected directly to the PHY chip.
> 
> This patch adds code for registering such LEDs when described in device
> tree and also adds a new private LED trigger called phydev-hw-mode.
> When this trigger is enabled for a LED, the various HW control modes
> which are supported by the PHY for given LED cat be get/set via hw_mode
> sysfs file.

> A PHY driver wishing to utilize this API needs to implement all the
> methods in the phy_device_led_ops structure.

Stale comment.

devm should take care of freeing, right?

Plus, format comments to 80 colums. checkpatch no longer warns, but rule still exists.
