patch "iio: adc: ad7124: fix DT configuration parsing" added to char-misc-linus

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

iio: adc: ad7124: fix DT configuration parsing

to my char-misc git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-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: adc: ad7124: fix DT configuration parsing

The cfg pointer is set before reading the channel number that the configuration should point to. This causes configurations to be shifted by one channel.
For example setting bipolar to the first channel defined in the DT will cause bipolar mode to be active on the second defined channel.

Fix by moving the cfg pointer setting after reading the channel number.
