[PATCH] samsung-laptop: fix config build error

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

Fix build failure when ACPI_VIDEO=m and SAMSUNG_LAPTOP=y.
The patch prevents that specific config combination.

drivers/built-in.o: In function `samsung_init':
samsung-laptop.c:(.init.text+0x128ff): undefined reference to `acpi_video_unregister'

ACPI_VIDEO=y, SAMSUNG_LAPTOP=m: OK
ACPI_VIDEO=y, SAMSUNG_LAPTOP=y: OK
ACPI=n, SAMSUNG_LAPTOP=y: OK
ACPI=n, SAMSUNG_LAPTOP=m: OK
