From: Randy Dunlap <rdun...@infradead.org>
Fix build errors in panel-samsung-s6e3ha2.c driver build. The driver
uses backlight interfaces so it should depend on BACKLIGHT_CLASS_DEVICE.
drivers/built-in.o: In function `s6e3ha2_remove':
panel-samsung-s6e3ha2.c:(.text+0xe49c2): undefined reference to
`backlight_device_unregister'
drivers/built-in.o: In function `s6e3ha2_probe':
panel-samsung-s6e3ha2.c:(.text+0xe4dad): undefined reference to
`backlight_device_register'
panel-samsung-s6e3ha2.c:(.text+0xe4e33): undefined reference to
`backlight_device_unregister'
