commit 0433ae556ec8 upstream version linux-5.5.y
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.

Without this patch certain wireless devices simply stop working since Linux 5.5.
Now queued up, thanks.
