From 5f33784a3570792db8f98fd351814775b04beeb9 Mon Sep 17 00:00:00 2001 From: Stefan Popa Date: Tue, 10 Sep 2019 17:44:21 +0300 Subject: [PATCH] iio: accel: adxl372: Fix push to buffers lost samples BugLink: https://bugs.launchpad.net/bugs/1848750 commit 62df81b74393079debf04961c48cb22268fc5fab upstream. One in two sample sets was lost by multiplying fifo_set_size with sizeof(u16). Also, the double number of available samples were pushed to the iio buffers.
