Subject: backlight users need to select BACKLIGHT_CLASS_DEVICE
From: Andy Whitcroft <apw@xxxxxxxxxxxx>
When compiling 2.6.19-rc2-mm1 we get the following link failures:
drivers/built-in.o(.init.text+0x3076): In function `toshiba_acpi_init':
: undefined reference to `backlight_device_register'
drivers/built-in.o(.exit.text+0x170): In function `toshiba_acpi_exit':
: undefined reference to `backlight_device_unregister'
When we build an ACPI module which provides backlight support we need to
ensure that the backlight class device is selected.
