A longstanding issue with genksyms is that it has hidden syntax errors.
For example, genksyms fails to parse the following valid code:
int x, __attribute__((__section__(".init.data")))y;
Here, only 'y' is annotated by the attribute, although I am not aware
of actual uses of this pattern in the kernel tree.
When a syntax error occurs, yyerror() is called. However,
error_with_pos() is a no-op unless the -w option is provided.
You can observe syntax errors by manually passing the -w option.
$ echo 'int x, __attribute__((__section__(".init.data")))y;' | scripts/genksyms/genksyms -w
<stdin>:1: syntax error
This commit allows attributes to be placed between a comma and
init_declarator.
