Subject: [PATCH] nl80211: Pass center frequency in kHz instead of MHz
Git-commit: b88d26d97c41680f7327e5fb8061ad0037877f40
Patch-mainline: v4.19-rc3
References: FATE#326294

freq_reg_info expects to get the frequency in kHz. Instead we
accidently pass it in MHz.  Thus, currently the function always
return ERR rule. Fix that.
