Hi Jonathan,
I see that this fix made it into 4.11-rc1 but not the 4.10.2 release.
Is this patch on track to appear in stable, or should I explicitly CC
[email protected] to pick this up?
Thanks,
William Breathitt Gray

I was half asleep and failed to tag this in the first place.
Send an email to [email protected] with the commit ID and a request
that it is picked up. Cc me.

Hello,
This patch was merged into Linus' tree as commit ca8d8e03b4c9 ("iio:
104-quad-8: Fix off-by-one error when addressing flag register"). This
fix should be merged into the 4.10 stable tree as well to fix an
off-by-one error which causes garbage data to be read as count values --
effectively preventing proper usage of the driver.
This patch fixes commit 28e5d3bb0325 ("iio: 104-quad-8: Add IIO support
for the ACCES 104-QUAD-8").
Thank you,
William Breathitt Gray
