Confused. Then how come smsc911x_drv_probe() has this line:quoted
acpi_handle *ahandle = ACPI_HANDLE(&pdev->dev);quoted
without any #ifdef's.There's a stub smsc911x_probe_config_acpi() provided in the non-ACPI case, Arnd's suggestion is basically to remove the stub.I think Catalin is referring to ACPI_HANDLE used without any #ifdefs Catalin, few macros like ACPI_HANDLE and ACPI_PTR are defined in include/linux/acpi.h even when CONFIG_ACPI is not set mainly to avoid #ifdef's around simple assignments like the above one and one in platform_driver.acpi_match_tableMy comment was to Graeme who said that #ifdef's were needed because acpi_handle (lowercase) was not defined in the !CONFIG_ACPI case. However, further down in the patch it was used without any #ifdef's.
Ah OK, I misunderstood. In that case Graeme statement is wrong. IIRC acpi_handle is not structure, it's just a ptr used for object references in ACPI namespace and is available even when !CONFIG_ACPI Regards, Sudeep
