Subject: Re: [PATCH 07/12] phylib: make local function static
The following functions are not used directly by any drivers:
phy_attach_direct
phy_device_create
phy_prepare_link
genphy_config_advert
genphy_setup_forced
phy_config_interrupt
phy_clear_interrypt
phy_sanitize_settings
phy_enable_interrupts
phy_disable_interrupts
Signed-off-by: Stephen Hemminger <shemminger@...tta.com>
---
Revised to keep get_phy_id which is used in one place in OF.
