This is kind of ugly.  Generally this should happen, but it does since you've
abused location in the MediaGalleryPrefInfo call site.  I'm not sure if there's
a cleaner way around, but it's worth thinking about.

[Lei Zhang, 2013/07/24 05:13:34]

Not sure what you mean. Let's chat tomorrow.

[Lei Zhang, 2013/07/29 20:48:27]

Ah, I think you were trying to say StorageInfo's |location_| should not include
the relative path from the path to device. I put the sub-folder display code
back where it was before.

+    CHECK(base_path.AppendRelativePath(base::FilePath(location_), &subfolder));
+  return GetDisplayNameForSubFolder(name, subfolder);
