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.

commit b82fcabe212a11698fd4b3e604d2f81d929d22f6 upstream.
If phy_pm_runtime_get_sync failed but we already
enable regulator, current code return directly without
doing regulator_disable. This patch fix this problem
and cleanup err handle of phy_power_on to be more readable.

commit 58a66dba1beac2121d931cda4682ae4d40816af5 upstream. If we reload phy-twl4030-usb, we get a warning about unbalanced pm_runtime_enable. Let's fix the issue and also fix idling of the device on unload before we attempt to shut it down. If we don't properly idle the PHY before shutting it down on removal, the twl4030 ends up consuming about 62mW of extra power compared to running idle with the module loaded.

for_each_available_child_of_node performs an of_node_get on each iteration,
so a return from the middle of the loop requires an of_node_put.
A simplified version of the semantic patch that finds this problem is as
follows (http://coccinelle.lip6.fr):
