Merge tag 'PTR_RET-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux

Pull PTR_RET() removal patches from Rusty Russell:
 "PTR_RET() is a weird name, and led to some confusing usage.  We ended
  up with PTR_ERR_OR_ZERO(), and replacing or fixing all the usages.

  This has been sitting in linux-next for a whole cycle"

[ There are still some PTR_RET users scattered about, with some of them
  possibly being new, but most of them existing in Rusty's tree too.  We
  have that

      #define PTR_RET(p) PTR_ERR_OR_ZERO(p)

  thing in <linux/err.h>, so they continue to work for now  - Linus ]

* tag 'PTR_RET-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux:
  GFS2: Replace PTR_RET with PTR_ERR_OR_ZERO
  Btrfs: volume: Replace PTR_RET with PTR_ERR_OR_ZERO
  drm/cma: Replace PTR_RET with PTR_ERR_OR_ZERO
  sh_veu: Replace PTR_RET with PTR_ERR_OR_ZERO
  dma-buf: Replace PTR_RET with PTR_ERR_OR_ZERO
  drivers/rtc: Replace PTR_RET with PTR_ERR_OR_ZERO
  mm/oom_kill: remove weird use of ERR_PTR()/PTR_ERR().
  staging/zcache: don't use PTR_RET().
  remoteproc: don't use PTR_RET().
  pinctrl: don't use PTR_RET().
  acpi: Replace weird use of PTR_RET.
  s390: Replace weird use of PTR_RET.
  PTR_RET is now PTR_ERR_OR_ZERO(): Replace most.
  PTR_RET is now PTR_ERR_OR_ZERO
