[PATCH 4.2 093/110] irqchip/tegra: Propagate IRQ type setting to parent

From: Greg Kroah-Hartman
Date: Fri Nov 06 2015 - 14:26:49 EST

4.2-stable review patch. If anyone has any objections, please let me know.


From: Lucas Stach <dev@xxxxxxxxxx>

commit 209da39154837ec1b69fb34f438041939911e4b4 upstream.

The LIC doesn't deal with the different types of interrupts itself
but needs to forward calls to set the appropriate type to its parent
IRQ controller.

Without this fix all IRQs routed through the LIC will stay at the
initial EDGE type, while most of them should actually be level triggered.
