[PATCH -next] leds: fix aat1290 build errors

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Fix build errors when LEDS_AAT1290=y and V4L2_FLASH_LED_CLASS=m
by restricting LEDS_AAT1290 to =m if V4L2_FLASH_LED_CLASS=m.

drivers/built-in.o: In function `aat1290_led_remove':
leds-aat1290.c:(.text+0xe5d77): undefined reference to `v4l2_flash_release'
drivers/built-in.o: In function `aat1290_led_probe':
leds-aat1290.c:(.text+0xe6494): undefined reference to `v4l2_flash_init'
