From 6cef2ab01636b6021044f349df466a97c408ec27 Mon Sep 17 00:00:00 2001 From: John Syne Date: Fri, 23 Mar 2018 11:25:48 -0300 Subject: staging:iio:ade7854: Fix the wrong number of bits to read Fixes: correctly handle the data size in the read operation for I2C The function ade7854_i2c_read_reg_32() have to invoke the i2c_master_recv() for read 32 bits values, however, the counter is set to 3 which means 24 bits. This patch fixes the wrong size of 24 bits, to 32 bits.
