Up to now s6e63m0_remove() returns zero unconditionally. Make it return void instead which makes it easier to see in the callers that there is no error to handle. Also the return value of spi remove callbacks is ignored anyway. Signed-off-by:

This tablet display is unique and hence must be added to documentation. Unfortunately, it's real make and number is not known due to obscure and missing documentation and lack of writing on the display assembly itself. So the natural alternative that came to mind is to name the panel after the device that contained it (an Android tablet). Hopefully that isn't an issue. I can confirm that the parameters that I've obtained are correct since they came from a dump of the original Android OS. Signed-off-by:
