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.
