Good point.

Explains why it breaks.  Thanks!

I left a bit too much unsaid there, but that was the point I was
making.  Ie, nothing of issue.

Incidently, it only took 14 hours of compiling to accomplish the
bisect.  And that was after a s/=m$/=n/. on my .27 .config.

Anyone bisecting should know that the new HID code is not bisect-safe.
The dell, lg, bright and sony hid drivers all are auto Y if hid is Y and
embedded is N and fail to link (when bisecting) due to missing symbols.
