struct mctelem_cookie missing definition

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Hi all,

I am looking through the few remaining MISRA violations that we have
left.  One of them is R11.2:

https://saas.eclairit.com:3787/fs/var/local/eclair/xen-project.ecdf/xen-project/hardware/xen/ECLAIR_normal/staging/X86_64/9118578464/PROJECT.ecd;/by_service/MC3A2.R11.2.html#{%22select%22:true,%22selection%22:{%22hiddenAreaKinds%22:[],%22hiddenSubareaKinds%22:[],%22show%22:false,%22selector%22:{%22enabled%22:true,%22negated%22:true,%22kind%22:0,%22domain%22:%22kind%22,%22inputs%22:[{%22enabled%22:true,%22text%22:%22violation%22}]}}}

Specifically, mctelem_cookie_t is a pointer to incomplete type and
therefore COOKIE2MCTE triggers a "conversion between a pointer to an
incomplete type and any other type".

mctelem_cookie_t is defined as:

typedef struct mctelem_cookie *mctelem_cookie_t;

I am looking through the code and I genuinely cannot find the definition
of struct mctelem_cookie.

If mctelem_cookie_t is only used as a pointer, wouldn't it make more
sense to do:

typedef struct mctelem_ent *mctelem_cookie_t;

?

What am I missing?

Cheers,

Stefano
