Unable to load WiFi module on Snowball board

[Alexjan Carraturo]

I'm using the stable-linux-ux500-3.4 branch of the kernel and I compiled it with the "u8500_defconfig"

The kernel was build correctly, and the modules too. I have to have the "CONFIG_SWITCH" to the defconfig to solve a compilation problem, and the DEVFS and NFS for my personal use.

The kernel starts well (I boot the kernel via tftp and the rootfs via NFS), and the board it's working, but, when I try to load the wifi module

#modprobe cw1200_wlan

I get this

[ 583.064819] cw1200_core: module is from the staging directory, the
quality is unknown, you have been warned.
[ 583.109039] cw1200_wlan: module is from the staging directory, the
quality is unknown, you have been warned.
[ 583.110351] platform cw1200_wlan: cw1200_clk_ctrl: Failed to get
clk 'sys_clk_out': -2

I report this on mailing list of "igloo-community" and they suggest to open a bug here.

I have tried this with 2 different rootfs: a openSUSE 12.2 rootfs and a self-compiled rootfs, with the same results.
