When implementing the USB2 testmode support via debugfs, Felipe has committed a mistake when counting the number of letters of some of the strings, resulting on an off by one error which prevented some of the Test modes to be entered properly. This patch, fixes that mistake. Signed-off-by: NGerard Cauvy <g-cauvy1@ti.com> Signed-off-by: NFelipe Balbi <balbi@ti.com>

Those transfer types are generally high bandwidth, so we want to optimize transfers with those endpoints. For that, databook suggests allocating 3 * wMaxPacketSize of FIFO. Let's do that. Signed-off-by: NFelipe Balbi <balbi@ti.com>

We need to dynamically re-size TxFifos for the cases where default values will not do. While at that, we create a simple function which, for now, will just allocate one full packet fifo space for each of the enabled endpoints. This can be improved later in order to allow for better throughput by allocating more space for endpoints which could make good use of that like isochronous and bulk.

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.
