kernel-doc emits a warning on struct_group_tagged() if you describe your
struct group member:
include/net/libeth/rx.h:69: warning: Excess struct member 'fp' description in 'libeth_fq'
The code:
/**
* struct libeth_fq - structure representing a buffer queue
* @fp: hotpath part of the structure
* @pp: &page_pool for buffer management
[...]
*/
struct libeth_fq {
struct_group_tagged(libeth_fq_fp, fp,
struct page_pool *pp;
[...]
);
When a struct_group_tagged() is encountered, we need to build a
`struct TAG NAME;` from it, so that it will be treated as a valid
embedded struct.
Decouple the regex and do the replacement there. As far as I can see,
this doesn't produce any new warnings on the current mainline tree.
