Subject: [PATCH 4.14 017/239] Input: synaptics-rmi4 - clear IRQ enables for F54

From: Lucas Stach <l.stach@...gutronix.de>

commit 549766ac2ac1f6c8bb85906bbcea759541bb19a2 upstream.

The driver for F54 just polls the status and doesn't even have a IRQ
handler registered. Make sure to disable all F54 IRQs, so we don't crash
the kernel on a nonexistent handler.
