Thanks for the patch and the detailed explanation. Everything here looks good to me. The patch itself was corrupted. I fixed it up by hand, but for future patches you might try 'git send-email', or if that won't work with your email provider you can use 'git format-patch' and attach the patch file. Also note that Signed-off-by should be capitalized. I fixed that when applying. Applied, thanks! _______________________________________________ wireless-regdb mailing list wireless-regdb@lists.infradead.org http://lists.infradead.org/mailman/listinfo/wireless-regdb
