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

    iio: adc: xilinx-ams: Fixed missing PS channels

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-testing 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 be merged to the char-misc-next branch sometime soon,
after it passes testing, and the merge window is open.

Subject: iio: adc: xilinx-ams: Fixed missing PS channels

The code forgot to increment num_channels for the PS channel inputs,
resulting in them not being enabled as they should.
