Wysocki Because acpi_bus_get_acpi_device() is completely analogous to acpi_fetch_acpi_dev(), rename it to acpi_get_acpi_dev() and add a kerneldoc comment to it. Accordingly, rename acpi_bus_put_acpi_device() to acpi_put_acpi_dev() and update all of the users of these two functions. While at it, move the acpi_fetch_acpi_dev() header next to the acpi_get_acpi_dev() header in the header file holding them. Signed-off-by: Rafael J.
