Agreed. The same fix is required:

Subject: [PATCH] phy: qcom-usb-hs: Add depends on EXTCON
We get the following compile errors if EXTCON is enabled as a
module but this driver is builtin:
drivers/built-in.o: In function `qcom_usb_hs_phy_power_off':
phy-qcom-usb-hs.c:(.text+0x1089): undefined reference to
`extcon_unregister_notifier'
drivers/built-in.o: In function `qcom_usb_hs_phy_probe':
phy-qcom-usb-hs.c:(.text+0x11b5): undefined reference to
`extcon_get_edev_by_phandle'
drivers/built-in.o: In function `qcom_usb_hs_phy_power_on':
phy-qcom-usb-hs.c:(.text+0x128e): undefined reference to `extcon_get_state'
phy-qcom-usb-hs.c:(.text+0x12a9): undefined reference to
`extcon_register_notifier'
so let's mark this as needing to follow the modular status of
the extcon framework.
