Hi Mani,
ath11k patch was sent as part of the same series to everybody included
in this patch as well
under the name of "[PATCH 2/2] wifi: ath11k: use unique QRTR instance ID".
If you did not receive it due to some kind of error, its available at
the linux-wireless patchwork[1]
or ath11k mailing list[2].
