the file in /drivers/gpu/drm/nouveau/core/subdev/i2c/aux.c is not allowed on windows machines. It is reserved for the operating system only. source:http://msdn.microsoft.com/en-us/library/windows/desktop/aa365247%28v=vs.85%29.aspx therefore editing the source on a windows machine is difficult. And Git throws errors because it cannot write the file. The solution to this is to rename it to auxiliary.c
This would be graphics. We've traditionally not cared, but with git now being a workable and not unusual environment for edit on windows, commit and build on the servers it's a good point Reassigning to the right category
