This is a note to let you know that I've just added the patch titled
iio: admv1013: add mixer_vgate corner cases
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: admv1013: add mixer_vgate corner cases
Include the corner cases in the computation of the MIXER_VGATE register
value.
According to the datasheet: The MIXER_VGATE values follows the VCM such
as, that for a 0V to 1.8V VCM, MIXER_VGATE = 23.89 VCM + 81, and for a >
1.8V to 2.6V VCM, MIXER_VGATE = 23.75 VCM + 1.25.
