I configured my text editor to remove trailing whitespaces 
automatically. That keeps my own patches free of them.  But the editor 
removes all trailing whitespaces, including those that have been there 
before. If I encounter such a case, I split out the whitespace fix and 
submit it separately.

But the work I do within fbdev is mostly for improving DRM. For the 
other issues in this file, I don't think that matroxfb should even be 
around any longer. Fbdev has been deprecated for a long time. But a 
small number of drivers are still in use and we still need its 
framebuffer console. So someone should either put significant effort 
into maintaining fbdev, or it should be phased out. But neither is 
happening.

Best regards
Thomas
