This is very useful for low level link testing where we might not have a USB Host stack, only a scope to verify signal integrity. Signed-off-by: NFelipe Balbi <balbi@ti.com>

Most link changes will, of course, happen with the help of a matching host HW, but in some cases we might want to debug very low level details about the link and exposing this to debugfs sounds like a good plan. This is a preparation for such setup. Signed-off-by: NFelipe Balbi <balbi@ti.com>

There are some situations were we might need to enable USB Test Modes without having access to a Host stack. In such situations we cannot rely solely on USB Control Messages to enable test features. For those cases, we will also allow test mode to be enabled via debugfs and this patch is a preparation for that. Signed-off-by: NFelipe Balbi <balbi@ti.com>

The assignment of handle in vmw_framebuffer_create_handle doesn't actually do anything useful and is incorrectly assigning an integer value to a pointer argument. It appears that this is a typo and should be dereferencing handle rather than assigning to it directly. This fixes a bug where an undefined handle value is potentially returned to user-space.

This reverts commit 87499ffd. Where is that paper bag ... ah here. I've failed to take an odd interaction between my other cleanups and this reclaim_buffers patch into account and also failed to properly test it. Looks like there are more dragons and hidden trapdoors in the drm release path than actual lines of code. Until I get a clue, let's just revert this.
