This is a temporary workaround for supporting multiple cards or AHB+PCI. There is ongoing upstream work to properly support this based of advertised FW features, but that is still ongoing. This is only supported on QCN9074 cards due to FW limitation, so HW ID is checked in order to prevent breaking QCA6390 and other popular cards. Signed-off-by: Robert Marko <robimarko@gmail.com>

Subject: [PATCH] wifi: ath11k: pci: fix compilation in 5.16 and older
|
|
|
|
Commit ("genirq/msi, treewide: Use a named struct for PCI/MSI attributes")
|
|
changed the msi_desc structure a bit, however that is only available in
|
|
kernels 5.17 and newer, so check for kernel version to allow compilation
|
|
in 5.16 and older.
