CHECKPATCH: strange warning on alignment modifier

Hi,

I have the following fragment of code:

+struct my_struct {
+ atomic_long_t l __aligned(sizeof(atomic_long_t));
+} __aligned(sizeof(atomic_long_t));


triggering this warning, when fed to checkpatch.pl:

WARNING: function definition argument 'atomic_long_t' should also have an identifier name
#19: FILE: path/to/file.h
+ atomic_long_t l __aligned(sizeof(atomic_long_t));


gcc [(Ubuntu 7.3.0-16ubuntu3) 7.3.0] seems to be happy about it

I am using the HEAD from mainline.

My intent is to specify the alignment of both the field and the structure (yes, probably redundant in this single-field case).

If I am doing something wrong, I can't figure out what it is, but I don't understand why the WARNING is mentioning a function definition.
