... except that it doesn't build:
drivers/acpi/arm64/iort.c: In function ‘arm_smmu_v3_resource_size’:
drivers/acpi/arm64/iort.c:837:21: error: ‘ACPI_IORT_SMMU_V3_CAVIUM_CN99XX’ undeclared (first use in this function)
if (smmu->model == ACPI_IORT_SMMU_V3_CAVIUM_CN99XX)
^
drivers/acpi/arm64/iort.c:837:21: note: each undeclared identifier is reported only once for each function it appears in
make[4]: *** [drivers/acpi/arm64/iort.o] Error 1
I don't see ACPI_IORT_SMMU_V3_CAVIUM_CN99XX defined, even in linux-next.
What's the plan here?
