| Subject: [PATCH] iio: chemical: pms7003: fix unmet triggered buffer dependency |
| |
| commit 217afe63ccf445fc220e5ef480683607b05c0aa5 upstream. |
| |
| IIO triggered buffer depends on IIO buffer which is missing from Kconfig |
| file. This should go unnoticed most of the time because there's a |
| chance something else has already enabled buffers. In some rare cases |
| though one might experience kbuild warnings about unmet direct |
| dependencies and build failures due to missing symbols. |
| |
| Fix this by selecting IIO_BUFFER explicitly. |
