It seems this has to be moved to an earlier place (e.g. subsys_initcall)
else the pinctrl core fails to find the pinctrl device at the device creation
time and bails out with -EPROBE_DEFER. Also, that device is never
created again, so -EPROBE_DEFER doesn't seem to work there.

Ah here, found your other comment :)

That's not needed, the real fix is to make twl-core.c and friends to
be regular module_init. There are already patches queued for that.

OK. I was testing with USB host driver and it seems to be loaded as fs_initcall() which
is the root of the problem. I will fix up the usb host driver to be loaded as module_init()
