This is a note to let you know that I've just added the patch titled
iio: orientation: hid-sensor-rotation: Add PM function (fix non
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: orientation: hid-sensor-rotation: Add PM function (fix non
working driver)
This fix makes newer ISH hubs work. Previous ones worked by lucky
coincidence.
Rotation sensor function does not work due to miss PM function.
Add common hid sensor iio pm function for rotation sensor.
Further clarification from Srinivas:
If CONFIG_PM is not defined, then this prevents this sensor to
function. So above commit caused this.
This sensor was supposed to be always on to trigger wake up in prior
external hubs. But with the new ISH hub this is not the case.
