Subject: [PATCH 4.4 39/60] phy: qcom-usb-hs: Add depends on EXTCON

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stephen Boyd <stephen.boyd@...aro.org>

commit 1a09b6a7c10e22c489a8b212dd6862b1fd9674ad upstream.

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.
