This is a note to let you know that I've just added the patch titled
iio:adc:qcom-spmi-vadc: add default scale to LR_MUX2_BAT_ID channel
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:adc:qcom-spmi-vadc: add default scale to LR_MUX2_BAT_ID channel
Checking at both msm8909-pm8916.dtsi and msm8916.dtsi from downstream
it is indicated that "batt_id" channel has to be scaled with the default
function:
chan@31 {
label = "batt_id";
reg = <0x31>;
qcom,decimation = <0>;
qcom,pre-div-channel-scaling = <0>;
qcom,calibration-type = "ratiometric";
qcom,scale-function = <0>;
qcom,hw-settle-time = <0xb>;
qcom,fast-avg-setup = <0>;
};
Change LR_MUX2_BAT_ID scaling accordingly.
