Second, the return codes of some functions were misleading or completely missing. This caused the driver to give wrong return codes also to the userspace. The series is based on top of 3.10rc1. I have tested the patch series on cardhu by running host1x and gr2d test cases (available at [0]). I would appreciate any help in testing/reviewing these patches.
