error compiling backports-3.14-1: too many arguments to function 'request_firmware_nowait'

[Javier Casas Marin <jcasas@wifense.com>]

Hi,
when I try to compile backports-3.14-1 in a 2.6.30 kernel I get this error:

/root/modules/backports-3.14-1/drivers/net/wireless/ath/ath9k/init.c: In 
function 'ath9k_eeprom_request':
/root/modules/backports-3.14-1/drivers/net/wireless/ath/ath9k/init.c:647: warning: 
passing argument 5 of 'request_firmware_nowait' makes pointer from 
integer without a cast

I saw that in backport-include/linux/firmware.h there is a pre-compiler 
directive to use the backport's version of request_firmware_nowait function:

#if defined(CPTCFG_BACKPORT_BUILD_FW_LOADER_MODULE)
#define request_firmware_nowait LINUX_BACKPORT(request_firmware_nowait)

But I haven't found where the CPTCFG_BACKPORT_BUILD_FW_LOADER_MODULE is 
defined.

I just ran:
make defconfig-ath9k
make

Am I missing a previous configuration step?

Thanks!
