From: Linus Walleij Date: Wed, 2 Sep 2015 19:02:58 +0000 (+0200) Subject: iio: st_accel: fix interrupt handling on LIS3LV02 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=61fd56309165d4790f99462d893b099f0b07312a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git iio: st_accel: fix interrupt handling on LIS3LV02 This accelerometer accidentally either emits a DRDY signal or an IRQ signal. Accidentally I activated the IRQ signal as I thought it was analogous to the interrupt generator on other ST accelerometers. This was wrong. After this patch generic_buffer gives a nice stream of accelerometer readings.
