[PATCH] mfd: tps65217: Drop call to irq_set_parent()

From: Guenter Roeck
Date: Fri Oct 14 2016 - 17:21:41 EST

The call to irq_set_parent() causes the following build error if tps65217
is built as module.

ERROR: ".irq_set_parent" [drivers/mfd/tps65217.ko] undefined!

The problem was introduced with commit 6556bdacf646f ("mfd: tps65217: Add
support for IRQs").

The author states: "I have added irq_set_parent() similarly as in
drivers/base/regmap/regmap-irq.c. But to be honest I am not sure what it
really does in case of tps65217."

So let's drop it.
