Though WCN6750 is a single PDEV device, it is not a DBS solution. So, do not put HW in DBS mode for WCN6750. Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00573-QCAMSLSWPLZ-1 Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1 Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.5.0.1-01100-QCAHKSWPL_SILICONZ-1 Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-00192-QCAHKSWPL_SILICONZ-1 Signed-off-by: Manikanta Pubbisetty <redacted> --- drivers/net/wireless/ath/ath11k/core.c | 2 +- drivers/net/wireless/ath/ath11k/wmi.c | 3 ++- 2 files changed, 3 insertions(+), 2 deletions(-)
