Subject[PATCH] iwlwifi: Fix build error in v2.6.25-5561-g064922a
I've just tried to compile v2.6.25-5561-g064922a and it failed with
these messages:

drivers/built-in.o: In function `iwl_leds_unregister_led':
iwl-led.c:(.text+0x7f14a): undefined reference to `led_classdev_unregister'
drivers/built-in.o: In function `iwl_leds_register_led':
iwl-led.c:(.text+0x7f220): undefined reference to `led_classdev_register'
make: *** [.tmp_vmlinux1] Error 1

and I checked that it was due to CONFIG_IWL4965_LEDS=y and
CONFIG_LEDS_CLASS=m in my .config.

If I CONFIG_LEDS_CLASS is also =y then it builds fine.

So I tried to cook up a patch to avoid that. It doesn't look
elegant but it avoids this problem for me :-)

Subject: [PATCH] iwlwifi: Fix build failure due to CONFIG_LEDS_CLASS=m

The compilation of v2.6.25-5561-g064922a fails with

drivers/built-in.o: In function `iwl_leds_unregister_led':
iwl-led.c:(.text+0x7f14a): undefined reference to `led_classdev_unregister'
drivers/built-in.o: In function `iwl_leds_register_led':
iwl-led.c:(.text+0x7f220): undefined reference to `led_classdev_register'
make: *** [.tmp_vmlinux1] Error 1

and this is the relevant part of .config which caused it

CONFIG_MAC80211_LEDS=y
CONFIG_IWLWIFI_LEDS=y
CONFIG_IWL4965_LEDS=y
CONFIG_LEDS_CLASS=m

The problem was that CONFIG_IWL_4965_LEDS was compiled in and
CONFIG_LEDS_CLASS was modular. To avoid this build failure
make IWL_4965_LEDS depend on LEDS_CLASS=y.
