Subject: [PATCH AUTOSEL 6.4 12/26] wifi: ath11k: add support default regdb while searching board-2.bin for WCN6855
From: Wen Gong <quic_wgong@...cinc.com>
[ Upstream commit 88ca89202f8e8afb5225eb5244d79cd67c15d744 ]
Sometimes board-2.bin does not have the regdb data which matched the
parameters such as vendor, device, subsystem-vendor, subsystem-device
and etc. Add default regdb data with 'bus=%s' into board-2.bin for
WCN6855, then ath11k use 'bus=pci' to search regdb data in board-2.bin
for WCN6855.
