Re: [PATCH] object_id.cocci: match only expressions of type 'struct object_id'

SZEDER Gábor [off-list ref] writes:

Most of our semantic patches in 'contrib/coccinelle/object_id.cocci'
turn calls of SHA1-specific functions into calls of their
corresponding object_id counterparts, e.g. sha1_to_hex() to
oid_to_hex().  These semantic patches look something like this:

  @@
  expression E1;
  @@
  - sha1_to_hex(E1.hash)
  + oid_to_hex(&E1)

and match the access to the 'hash' field in any data type, not only in
'struct object_id', and, consquently, can produce wrong
transformations.

Thanks, will queue.
