patch "iio: chemical: pms7003: fix unmet triggered buffer dependency" added to staging-linus

[gregkh]

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.

Subject: iio: chemical: pms7003: fix unmet triggered buffer dependency

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.
