Hello, I have looked at the source file for the ACPI fan driver once more. I would appreciate if a specific implementation detail can be clarified there. Static source code analysis can point out that functions like the following share an approach for error detection and corresponding exception handling. * acpi_fan_get_fif * acpi_fan_get_fps * fan_get_state_acpi4 https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/tree/drivers/acpi/fan.c?id=80c75a0f1d81922bf322c0634d1e1a15825a89e6#n107 Can it matter eventually to handle a detected null pointer differently from further checks for an attribute like "obj->type" or "obj->package"?
