Subject: [PATCH] ath11k: store and send country code to firmware after recovery
Git-commit: b2beae327e039736299f3c6559f3467323fe68c5
Patch-mainline: v5.19-rc1
References: bsc#1206451
Currently ath11k does not send the country code to firmware after device
recovery, as a result the regdomain info is reported from firmware by
default. Regdomain info is important, so ath11k also need to restore
it to the value which was used before recovery.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3
