Merge tag 'libnvdimm-fixes-4.18-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm fixes from Dave Jiang: - ensure that a variable passed in by reference to acpi_nfit_ctl is always set to a value. An incremental patch is provided due to notice from testing in -next. The rest of the commits did not exhibit issues. - fix a return path in nsio_rw_bytes() that was not returning "bytes remain" as expected for the function. - address an issue where applications polling on scrub-completion for the NVDIMM may falsely wakeup and read the wrong state value and cause hang. - change the test unit persistent capability attribute to fix up a broken assumption in the unit test infrastructure wrt the 'write_cache' attribute - ratelimit dev_info() in the dax device check_vma() function since this is easily triggered from userspace * tag 'libnvdimm-fixes-4.18-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: nfit: fix unchecked dereference in acpi_nfit_ctl acpi, nfit: Fix scrub idle detection tools/testing/nvdimm: advertise a write cache for nfit_test acpi/nfit: fix cmd_rc for acpi_nfit_ctl to always return a value dev-dax: check_vma: ratelimit dev_info-s libnvdimm, pmem: Fix memcpy_mcsafe() return code handling in nsio_rw_bytes()
