The 'wcove' short word is not used in this patch.
If the author want to use the 'wcove', I recommend that
you should use the 'wcove' instead of 'wc' in this patch.

And, I think that  'pwrsrc' is not ambiguous.
Hans might use the 'pwrsrc' as the 'Power Source'.
But, this driver is not power source. Instead,
this driver supports the detection of external connector.

I think 'power source' means the power supply instead of detector.
