Using kernel 3.15.8-200.fc20.x86_64, the accelerometer works as intended with the Thinkpad Twist.
However, using rawhide kernel 3.16.0-1.fc22.x86_64, I get Resource temporarily unavailable when trying to read from the accelerometer.
I tried to report this in the upstream kernel bugzilla, but I couldn't find the right component, so I filed it here. If you know what is the right component in the upstream bugzilla, let me know.
This is using:
to read from the IIO sensor.
Those are the errors:
This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle.
Changing version to '22'.

*********** MASS BUG UPDATE **************
We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 22 kernel bugs.
Fedora 22 has now been rebased to 4.2.3-200.fc22. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.
If you have moved on to Fedora 23, and are still experiencing this issue, please change the version to Fedora 23.
If you experience different issues, please open a new bug report for those.
Elad, best send this to the IIO mailing-list if it still happens.
No, it has been fixed upstream long ago.
