4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Samasth Norway Ananda <samasth.norway.ananda@xxxxxxxxxx>
[ Upstream commit c636fa85feb450ca414a10010ed05361a73c93a6 ]
The band_idx variable in the function wlc_lcnphy_tx_iqlo_cal() will
never be set to 1 as BCM4313 is the only device for which the LCN PHY
code is used. This is a 2G-only device.
Fixes: 5b435de0d786 ("net: wireless: add brcm80211 drivers")
