Okay, so this is a good idea, and for that,

However, it's *not* a good idea for the purpose of registering the lpsp
debugfs file for every connector out there. There's no point in that, at
all. You need to register the file only when it makes sense in
intel_connector_debugfs_add(), and not for every conceivable connector
out there.
And your igt test absolutely *must* check if the debugfs is there or
not, and handle it gracefully.
