Compile errors come from ARM plaform:
In file included from drivers/net/wireless/ath/ath6kl/init.c:19:0:
include/linux/of.h: In function ‘of_property_read_u32_array’:
include/linux/of.h:249:10: error: ‘ENOSYS’ undeclared

In my opinion this is a bug in of.h and I sent a patch few weeks ago:

https://lkml.org/lkml/2011/10/6/133

But it seems that openfirmware maintainers don't care as I haven't
received any reply to the patch. So let's just workaround this in ath6kl.

Patch applied, but I changed the commit log a bit. Thank you again.

    ath6kl: Fix compilation error from of.h

    When compiling ath6kl for ARM with device tree tree compilation fails
    with errors like:

    include/linux/of.h: In function 'of_property_read_u32_array':
    include/linux/of.h:249:10: error: 'ENOSYS' undeclared

    Workaround this by including errno.h from init.c.

    kvalo: improved commit log
