Subject: [PATCH 4.17 13/46] iio: mma8452: Fix ignoring MMA8452_INT_DRDY
Date: Fri, 6 Jul 2018 07:46:34 +0200 [thread overview]
Message-ID: <20180706054525.239318637@linuxfoundation.org> (raw)
In-Reply-To: <20180706054524.595521988@linuxfoundation.org>
4.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Leonard Crestez <leonard.crestez@nxp.com>
commit b02ec67a8e38875cdc5f9214be885022f11c0017 upstream.
Interrupts are ignored if no event bit is set in the status status
register and this breaks the buffer interface. No data is shown when
running "iio_generic_buffer -n mma8451 -a" and interrupt counts go
crazy.
Fix by not returning IRQ_NONE if DRDY is set.
Fixes: 605f72de137a ("iio: accel: mma8452: improvements to handle
multiple events")
