| Subject: staging:iio:ade7854: Fix the wrong number of bits to read |
| |
| commit 6cef2ab01636b6021044f349df466a97c408ec27 upstream. |
| |
| 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. |
