From 7e0541b25702ccaa9560bdd2441caedca2d438e9 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Sun, 10 Jan 2021 18:29:45 -0800 Subject: [PATCH] Input: omap4-keypad - disable unused long interrupts We are not using the long events and they produce extra interrupts. Let's not enable them at all. Note that also the v3.0.8 Linux Android kernel has long interrupts disabled.
