Hi all,
After merging the cxl tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
drivers/nvdimm/label.c:750:32: error: 'uuid_to_nvdimm_cclass' defined but not used [-Werror=unused-function]
750 | static enum nvdimm_claim_class uuid_to_nvdimm_cclass(uuid_t *uuid)
| ^~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
Caused by commit
d68bc4b2338b ("libnvdimm/labels: Add address-abstraction uuid definitions")
Exposed by commit
3fe617ccafd6 ("Enable '-Werror' by default for all kernel builds")
I have applied the following patch for today.
