So of these cases might arguably be worth doing, but extreme care is needed to ensure
that the code is not broken.
Also, you are modifiying userspace ABI here so another level of care is needed.
To approach this sort of change I would suggest an RFC for the proposed ABI
changes.
In this particular case the driver is so far from standard ABI that you would
likely get the response that it needs to conform to standard ABI rather than
fixing it's own random choices of what sysfs files should be called.
