Subject: checkpatch.pl: add union and struct to the exceptions list
X-Git-Tag: v2.6.34-rc1~68
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=22fd2d3e4f75a2596ccdfdcbdfd505c9c60bf346;p=pandora-kernel.git

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.
