Subject: mfd: Set twl4030-irq tertiary interrupts to be nested/threaded.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b18d1f0f490cbeefd389ccd90504dd6501e6d493;p=linux-beck.git

mfd: Set twl4030-irq tertiary interrupts to be nested/threaded.

As tertiary interrupts are handled by handle_twl4030_sih calling
handle_nested_irq, they do not need their own separate irq thread.
So mark them as 'nested_thread' interrupts to avoid the extra thread
creation.

Tested on GTA04 Pheonux.
