The tilcdc driver could be compiled as a module, but was severely broken and could not be used as such. This patchset attempts to fix the issues preventing a proper load/unload of the module.
Issues included dangling sysfs nodes, dangling devices, memory leaks and a double kfree.
It now seems to be working ok. We have tested this by loading and unloading the driver repeteadly, with both panel and slave connectors and found no flaws.
There is still one warning left on tilcdc_crtc_destroy, caused by destroying the connector while still in an ON status. We don't know why this happens or why it's an issue, so we did not fix it.
The first 7 patches are bug fixes which and should probably be applied in the stable trees. The last two are clean-ups.
The series applies cleanly over -next and 3.15-rc8, and will be resent for v3.16-rc1, once it's out.
