[GIT PULL] NVDIMM and DAX for 7.4

[GIT PULL] NVDIMM and DAX for 7.4

[Alison Schofield]

Hi Linus,

Please pull to receive NVDIMM and DAX changes for 7.4:

    git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm.git tags/libnvdimm-for-7.4

This is a small set of fixes: error handling corrections in the DAX
core and bus code, a fix to the DAX file range comparison helpers, and
two libnvdimm/pmem fixes for error and probe failure paths.

These have all appeared in -next for at least 6 days.

Thank-you,
Alison
