The gcc extension for binary constants that start with 0b is only supported with gcc version 4.3 or higher.

2013-04-29checkpatch: only warn for empty lines before closing braces by themselvesMatthijs Kooijman
This check was intended to catch extra newlines at the end of a function definition, but it would trigger on any closing brace, including those of inline functions and macro definitions, triggering false positives.
