This is a note to let you know that I've just added the patch titled

iio: chemical: pms7003: fix unmet triggered buffer dependency

to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

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.
