Hi Darren Hart I double checked no compile fail on my side. And could you check if enable config option " CONFIG_INTEL_PMC_IPC", Seems the error is due to this, please check intel_pmc_ipc.h for detail Thanks And by using checkpatch.pl, found there is really warning as below I will sent update one Great thanks:) qzha $ scripts/checkpatch.pl 0001-platform-x86-add-Intel-Broxton-PMC-IPC-driver.patch WARNING: added, moved or deleted file(s), does MAINTAINERS need updating? #21: new file mode 100644 WARNING: 'resoures' may be misspelled - perhaps 'resources'? #207: FILE: drivers/platform/x86/intel_pmc_ipc.c:69: + * but export multi resoures on one ACPI device(IPC) for total: 0 errors, 2 warnings, 863 lines checked 0001-platform-x86-add-Intel-Broxton-PMC-IPC-driver.patch has style problems, please review.
