target: tcm_mod_builder: small fixups
Browse files Browse the repository at this point in the history 
This includes:
- remove on _ in "__NAMELEN" in $fabric _make_tport
- target_fabric_configfs_init() returns an error pointer and not NULL
  anymore. Consider that.
- replace (!(var_name)) with (!var_name). The extra () are not required
- remove #ifdef MODULE. If the code is builtin it needs an init function
  or the code is useless
- put exit/clean functions into __exit
