For the CL description, I'd go for something like

MacViews: Fix auto raw pointer deduction in extension_popup.cc.

This is a compile error since r454453.
 error: [chromium-style] auto variable type must not deduce to a raw
  pointer type.

BUG=425229

This doesn't follow the patterns established in 
https://groups.google.com/a/chromium.org/forum/#!msg/chromium-dev/PMxDx7eR_YY...

I think we want auto* here.
