Hi all, After merging the phy-next tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/phy/phy-can-transceiver.c: In function 'can_transceiver_phy_power_on': drivers/phy/phy-can-transceiver.c:35:9: error: implicit declaration of function 'mux_state_select'; did you mean 'mux_control_select'?
