| Subject: [PATCH] staging: iio: ad7606: fix improper setting of oversampling |
| pins |
| |
| commit b321a38d2407c7e425c54bc09be909a34e49f740 upstream. |
| |
| The oversampling ratio is controlled using the oversampling pins, |
| OS [2:0] with OS2 being the MSB control bit, and OS0 the LSB control |
| bit. |
| |
| The gpio connected to the OS2 pin is not being set correctly, only OS0 |
| and OS1 pins are being set. Fix the typo to allow proper control of the |
| oversampling pins. |
