Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1396671]
Comment 2 Justin M. Forbes 2016-11-21 12:44:10 EST 
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 00:47:06 EST 
Righto, will close that up.  There was enough CONFIG_EXYNO in the fedora kernels that it was affected.
