+From ec701fa986108fae10bee7cfe269e12210521c5f Mon Sep 17 00:00:00 2001
+From: Golan Ben Ami <golan.ben.ami@intel.com>
+Date: Wed, 18 Mar 2020 08:12:54 +0200
+Subject: iwlwifi: don't send GEO_TX_POWER_LIMIT if no wgds table
+
+The GEO_TX_POWER_LIMIT command was sent although
+there is no wgds table, so the fw got wrong SAR values
+from the driver.
+
+Fix this by avoiding sending the command if no wgds
+tables are available.
