Please update this comment - have you got it that IsPlatformSettingEnabled() now
returns true in the legacy case (if there is no Google Location Settings)?

[Ramya, 2012/10/22 23:57:11]

Yes, this works in the legacy case as well.

+  // If 'Allow' we follow the regular flow.
+  if (google_location_settings_helper_->IsPlatformSettingEnabled())
+    return GeolocationConfirmInfoBarDelegate::Accept();
+
+  // If 'Google Location Settings', we need to open the system Google Location
+  // Settings activity.
+  google_location_settings_helper_->ShowGoogleLocationSettings();
+  SetPermission(false, false);
+  return true;
 }
