I did get warnings below when I compile, then I remove Werror.
ah_os.c: In function `ath_hal_reg_write':
ah_os.c:331: warning: passing arg 2 of `__writel' makes integer from
pointer without a cast
ah_os.c: In function `ath_hal_reg_read':
ah_os.c:340: warning: passing arg 1 of `__readl' makes integer from
pointer without a cast
My board is able to run madwifi-old without any problem, but when I move
to madwifi-ng, haven't get any luck with mulitple revisions. Any help is
highly appreciated.
Thanks!
