Two firmware workarounds for WCN3990 (QCA6174 integrated variant on Qualcomm SM8150/SDM845 platforms) running WLAN.HL.3.2 firmware. Both issues are firmware bugs where WCN3990 advertises capabilities it cannot handle correctly. Tested on OnePlus 7T (SM8150) with WLAN.HL.3.2.0.c2-00006 and WLAN.HL.3.2.0.c2-00011. Patch 1 fixes a deterministic firmware crash caused by the quiet mode WMI command. The existing guard from commit 53884577fbcef relied on THERM_THROT not being advertised, but HL3.2 now advertises it despite still crashing on the command. Patch 2 works around a bug where active scan does not tune the radio on 5GHz non-DFS channels, making 5GHz networks invisible. Forcing passive scan mode restores 5GHz discovery.
