Merge branch 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild 

Pull kbuild misc changes from Michal Marek:
 "In the non-critical part of kbuild, I have
   - Some make coccicheck improvements and two new tests
   - Support for a cleaner html output in scripts/kernel-doc, named
     html5 (no, it does not play videos, yet)

  BTW, Randy wants to route further kernel-doc patches through the
  kbuild tree."

* 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  Update SmPL/Coccinelle section of MAINTAINERS
  coccicheck: Add the rep+ctxt mode
  scripts/coccinelle/tests/odd_ptr_err.cocci: semantic patch for IS_ERR/PTR_ERR inconsistency
