| Subject: iio: adc: ab8500-gpadc: Fix off by 10 to 3 |
| |
| From: Linus Walleij <linus.walleij@linaro.org> |
| |
| commit 4f5434086d9223f20b3128a7dc78b35271e76655 upstream. |
| |
| Fix an off by three orders of magnitude error in the AB8500 |
| GPADC driver. Luckily it showed up quite quickly when trying |
| to make use of it. The processed reads were returning |
| microvolts, microamperes and microcelsius instead of millivolts, |
| milliamperes and millicelsius as advertised. |
