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
