#ifdef CONFIG_ checks not working

Hi,
I just noticed that with the 2.6.36-rc8 kernel, the #ifdef checks aren't working.

So for example, if I add the following code fragment in my omap3_beagle_init function, CONFIG_WL1271 doesn't get detected, even though in my .config file, CONFIG_WL1271=m.

This way, the mux settings might also fail, right, which might be the source of a few of the problems that I'm facing.

Would you happen to know why this is not working. This type of checks used to work with the 2.6.32 kernel versions.

#ifdef CONFIG_WL1271
printk(KERN_INFO "%s: CONFIG_WL1271 detected\n", __func__);
#else
printk(KERN_INFO "%s: CONFIG_WL1271 not detected\n", __func__);
#endif

Boot message:

[ 0.000000] omap3_beagle_init: CONFIG_WL1271 not detected

Best regards,

Elvis Dowson
