I was referring to the ALL_KMODS feature in OpenWrt, not to the
PTP_1588_CLOCK_OPTIONAL symbol.  As noted, there are many similar
constructs in the kernel. Personally I think
PTP_1588_CLOCK || PTP_1588_CLOCK=n would have been better, but I
see your point and am definitely not going to argue about that ;-)

Should have made it clearer that I believe the bug is in OpenWrt, not in
the kernel. Just didn't notice that you were CC'ed into the discussion.
Thought we were having an OpenWrt conversation... Sorry about the
confusion.
