checkpatch.pl: add union and struct to the exceptions list
Here is a small code snippet, which will be complained about by
checkpatch.pl:
#define __STRUCT_KFIFO_COMMON(recsize, ptrtype) \
union { \
struct { \
unsigned int in; \
unsigned int out; \
}; \
char rectype[recsize]; \
ptrtype *ptr; \
const ptrtype *ptr_const; \
};
This construct is legal and safe, so checkpatch.pl should accept this. It
should be also true for struct defined in a macro.
Add the `struct' and `union' keywords to the exceptions list of the
checkpatch.pl script, to prevent error message "Macros with multiple
statements should be enclosed in a do - while loop". Otherwise it is not
possible to build a struct or union with a macro.
