I think it's hard to do that because these definitions are part of the user space API. include/uapi/linux/wireless.h linux-wireless is not on the CC list so we will never know for sure. There are still a bunch of these warnings. drivers/staging/rtl8192u/r8192U_wx.c:271 rtl8180_wx_get_range() warn: assigning (-78) to unsigned variable 'range->avg_qual.level' drivers/staging/rtl8712/rtl871x_ioctl_linux.c:914 r8711_wx_get_range() warn: assigning (-78) to unsigned variable 'range->avg_qual.level' drivers/net/wireless/ipw2x00/ipw2100.c:6817 ipw2100_wx_get_range() warn: assigning (-78) to unsigned variable 'range->avg_qual.level' drivers/net/wireless/hostap/hostap_ioctl.c:1023 prism2_ioctl_giwrange() warn: assigning (-60) to unsigned variable 'range->avg_qual.level' drivers/net/wireless/prism54/isl_ioctl.c:451 prism54_get_range() warn: assigning (-80) to unsigned variable 'range->avg_qual.level' drivers/staging/rtl8192u/r8192U_core.c:4493 rtl8192_rx_nomal() warn: assigning (-98) to unsigned variable 'stats.noise' drivers/staging/rtl8192u/r8192U_core.c:4605 rtl8192_rx_cmd() warn: assigning (-98) to unsigned variable 'stats.noise' drivers/staging/rtl8192u/r8192U_wx.c:266 rtl8180_wx_get_range() warn: assigning (-98) to unsigned variable 'range->max_qual.noise' drivers/staging/rtl8192e/rtl8192e/rtl_wx.c:1323 r8192_get_wireless_stats() warn: assigning (-100) to unsigned variable 'wstats->qual.noise' drivers/staging/rtl8192e/rtl8192e/rtl_core.c:2322 rtl8192_rx_normal() warn: assigning (-98) to unsigned variable 'stats.noise' drivers/net/wireless/hostap/hostap_ioctl.c:1024 prism2_ioctl_giwrange() warn: assigning (-95) to unsigned variable 'range->avg_qual.noise' regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
