[PATCH 1/3] Input: omap4-keypad - disable unused long interrupts

From: Tony Lindgren
Date: Wed Mar 18 2020 - 18:57:45 EST


We are not using the long interrupts 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.
