HI, all
When reviewing function mei_me_cl_rm_by_uuidï I notice that function
__mei_me_cl_by_uuid increases me_cl refcount
and function _mei_me_cl_del delete a list node with decrement me_cl
refcount , actually here cause a refcount leak as we haven't release
the refcount
by __mei_me_cl_by_uuid ?
similar issue happens in mei_me_cl_rm_by_uuid_id too.

void mei_me_cl_rm_by_uuid(struct mei_device *dev, const uuid_le *uuid)
{
struct mei_me_client *me_cl;

dev_dbg(dev->dev, "remove %pUl\n", uuid);

down_write(&dev->me_clients_rwsem);
me_cl = __mei_me_cl_by_uuid(dev, uuid); /* increase a refcount */
__mei_me_cl_del(dev, me_cl); /* release the refcount with a list
node deteled */
up_write(&dev->me_clients_rwsem);
}

Best regards,

Lin Yi.
