Subject: [PATCH net-next v2] net: phy: air_en8811h: reset netdev rules when
 LED is set manually

Setting LED_OFF via brightness_set should deactivate hw control, so make
sure netdev trigger rules also get cleared in that case.
This fixes unwanted restoration of the default netdev trigger rules and
matches the behaviour when using the 'netdev' trigger without any
hardware offloading.

Fixes: 71e79430117d ("net: phy: air_en8811h: Add the Airoha EN8811H PHY driver")
Signed-off-by: Daniel Golle <daniel@...rotopia.org>

v2: send to net-next instead of net tree because driver is present only
    in net-next tree. Improve commit description while at it.
