Is this implemented in the options UI? I only see changes in md-settings.

[sammiequon, 2016/12/08 03:50:50]

It's meant to be md-settings only, but it has to be under the lock_screen.html
which is options only, so I add the data to options as well. Is there a better
approach?

[stevenjb, 2016/12/08 16:49:41]

Is this used in this CL? If so I missed it. If not, it should be added in the CL
that uses it.

[sammiequon, 2016/12/08 20:22:40]

Yes, lock_screen.html was added previously so this CL only needs to set the
appropriate data.

[stevenjb, 2016/12/08 20:50:21]

Could you go ahead and separate those changes from this CL then? Thanks.

[sammiequon, 2016/12/08 21:44:01]

Hmmm, maybe I didn't explain properly in the previous comments. Originally I
meant for this to be md-settings only but the trybots would not pass because
lock_screen.html is in both md-settings and options and fingerprint_list.html is
inside lock_screen.html. So I added this to the fingerprint resources to options
as well (to get the trybots working). I'm told md-settings for chromeOS may not
be ready in time so I tested that this works on options. 

But if you did understand, how do I seperate the options stuff and still pass
the trybots? Thanks a bunch!

We should make sure this works in both options and md-settings. Please test in
both - I expect that options will pretty much just work, though. I'm not sure
the current timeline for md-settings on CrOS, but md-settings has been delayed a
few times now.
