patch "iio: tmp006: Check channel info on write" added to staging-linus

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!
