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

iio: adc: Fix incorrect exit of for-loop

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.

Currently the for-loop that scans for the optimial adc_period iterates through all the possible adc_period levels because the exit logic in the loop is inverted. I believe the comparison should be swapped and the continue replaced with a break to exit the loop at the correct point.
