ne,

+ 	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.
