I got the following compiling kernel 3.1-rc3 on x86_64 with CONFIG_ACPI_DOCK=n: drivers/ata/libata-acpi.c: In function 'ata_acpi_associate': drivers/ata/libata-acpi.c:266:11: warning: passing argument 2 of 'register_hotplug_dock_device' discards 'const' qualifier from pointer target type [enabled by default] include/acpi/acpi_drivers.h:146:19: note: expected 'struct acpi_dock_ops *' but argument is of type 'const struct acpi_dock_ops *' drivers/ata/libata-acpi.c:275:11: warning: passing argument 2 of 'register_hotplug_dock_device' discards 'const' qualifier from pointer target type [enabled by default] include/acpi/acpi_drivers.h:146:19: note: expected 'struct acpi_dock_ops *' but argument is of type 'const struct acpi_dock_ops *' The two versions of register_hotplug_dock_device() in acpi_drivers.h, depending on CONFIG_ACPI_DOCK, differ in whether the 2nd parameter is const or not. The dummy version for !DOCK lacked the const, causing the warning. Trivially fixed by adding the const.
