Hey there,

Is this syntax OK for Makefile use? I'm only asking out of personal  
ignorance and because I'd use:

Kconfig:

config LZO1X_COMPRESS
	select LZO1X
	tristate

config LZO1X_DECOMPRESS
	select LZO1X
	tristate

config LZO1X
	tristate (or boolean??)

Makefile:

obj-$(CONFIG_LZO1X) += lzo1x/

Thanks,

Michael-Luke
