[PATCH] checkpatch: support function pointers for unnamed function definition arguments

From: Miles Chen
Date: Wed Sep 13 2017 - 23:01:35 EST


Current unnamed function definition argument does not include function
pointer cases and it reports warnings like:

WARNING: function definition argument 'void' should also have an identifier name
+unsigned int (*dummy)(void);

Support function pointers for unnamed function arguments.
