Hello, Andy! I know about DECLARE_BITMAP(), it is a very useful macro for bitmaps that are over 32 bits, which is absolutely not the case here. This macro will make code more difficult to read and then we will have to use the bitmap API, which is unnecessary overhead for this case, and thus, it won't be an improvement anymore, IMO. I'd either keep this patch as-is or drop it.
