Subject[PATCH] ACPI: Fix CONFIG_ACPI_DOCK=n compiler warning
Date
Recently the ACPI ops structs were constified but the inline version
of register_hotplug_dock_device() was overlooked (see also commit
9c8b04be443b33939f374a811c82abeebe0a61d1, June 25 2011). Update
the inline function register_hotplug_dock_device() that is
enabled with CONFIG_ACPI_DOCK=n too. This patch fixes at
least the following compiler warnings:

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 qualifiers from pointer target type
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 qualifiers from pointer target type
include/acpi/acpi_drivers.h:146:19: note: expected .struct acpi_dock_ops *. but argument is of type .const struct acpi_dock_ops *.
