Hi all, After merging the pm tree, today's linux-next build (x86_64 allmodconfig) failed like this: ERROR: modpost: "acpi_device_dep" [drivers/platform/surface/surface_acpi_notify.ko] undefined! Caused by commit 90d843b96b49 ("ACPI: utils: Introduce helper for _DEP list lookup") I have used the pm tree from next-20231218 for today. -- Cheers, Stephen Rothwell
