Subject: checkpatch: fix false errors due to macro concatenation
From: Andy Whitcroft <apw@xxxxxxxxxxxxx>
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.
