Subject: iio: st_accel: fix interrupt handling on LIS3LV02
From: Linus Walleij <linus.walleij@xxxxxxxxxx>
commit 61fd56309165d4790f99462d893b099f0b07312a upstream.
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.
