From aef3ef165972ca16e3b87ec024e6edfad642e230 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Fri, 2 Apr 2021 19:45:40 +0100 Subject: [PATCH] iio:adc:nau7802: Use IRQF_NO_AUTOEN instead of request then disable Whilst a race during interrupt enabling is probably not a problem, it is better to not enable the interrupt at all. The new IRQF_NO_AUTOEN flag allows us to do that.
