Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1396671]

Comment 2 Justin M. Forbes 2016-11-21 17:44:10 UTC

Not sure why we have a bug on this, the driver in question is in an upstream android tree at google, but not in Linus' linux kernel tree. Fedora doesn't ship this driver.

Comment 3 Wade Mealing 2016-11-28 05:47:06 UTC

Righto, will close that up.  There was enough CONFIG_EXYNO in the fedora kernels that it was affected.
