Yes, but: 1. This would work only for newer kernels. 2. This little patch allows to work on older kernels, at least somehow. > IIRC chazy had a hacked-together patch for that at some point.

At least RaspberryPi 2, as far as i know. Also i am testing on some Samsung proprietary HW which has the same problem.
