This is a note to let you know that I've just added the patch titled
iio: tmp006: Check channel info on write
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: tmp006: Check channel info on write
only SAMP_FREQ is writable
Will lead to SAMP_FREQ being written by any attempt to write
to the other exported attributes and hence a rather unexpected
result!
