checkpatch: fix false errors due to macro concatenation
The macro concatenation (##) sequence can cause false errors when checking macro's. Checkpatch doesn't currently know about the operator. For example this line, + entry = (struct ftrace_raw_##call *)raw_data; \ is correct but it produces the following error, ERROR: need consistent spacing around '*' (ctx:WxB) + entry = (struct ftrace_raw_##call *)raw_data;\ ^ The line above doesn't have any spacing problems, and if you remove the macro concatenation sequence checkpatch doesn't give any errors. Extend identifier handling to include ## concatenation within the definition of an identifier.
