From 4efdfbc16cceffbcb29e53a5be55d83a4c76a9c0 Mon Sep 17 00:00:00 2001 From: Jakob Hauser Date: Fri, 12 Aug 2022 23:54:07 +0200 Subject: [PATCH] iio: magnetometer: yas530: Change range of data in volatile register In function yas5xx_volatile_reg(), register "YAS5XX_MEASURE_DATA + 8" shouldn't be volatile as we count from 0 to 7 here. Instead of lowering the number from 8 to 7, the operator "<=" is replaced by "<". The size of the measure data array is 8, therefore it's more natural to use 8 as a constant. This change is of low importance as the "+ 8" register isn't called.
