From 5e068069319a9fb02fb14337c2cedeae5f16d812 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Wed, 6 Aug 2014 16:09:53 -0700 Subject: lib: bitmap: make nbits parameter of bitmap_equal unsigned The compiler can generate slightly smaller and simpler code when it knows that "nbits" is non-negative. Since no-one passes a negative bit-count, this shouldn't affect the semantics.
