| Subject: [PATCH] iio: accel: adxl372: Fix push to buffers lost samples |
| |
| 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. |
