Subject: mfd: Use request_threaded_irq for twl4030-irq instead of irq_set_chained_handler
X-Git-Tag: v3.2-rc7~14^2~1

mfd: Use request_threaded_irq for twl4030-irq instead of irq_set_chained_handler

irq_set_chained_handler sets 'desc->handle_irq'.
However this irq is called by handle_nested_irq from handle_twl4030_pih,
and that uses action->thread_fn.

So the handled set with irq_set_chained_handler is never called.

So change to use request_threaded_irq instead - that sets the correct field.

Tested on GTA04 Phoenux.
