vt6655 (PCI) and vt6656 (USB) do only support 2.4GHz band and not 5GHz band. Both drivers do allow only one vendor id and device id. So no other devices are covered by those drivers. Because of this the following priv->rf_type cannot occure: RF_AIROHA7230 RF_VT3342A0 --- Tested with vt6656 on mini PCIe card (connected over USB) which is using rf_type: RF_VT3226D0 (2.4GHz only) Tested with vt6656 as USB Plugin Module which is using rf_type: RF_AL2230S (2.4GHz only) In order to combine vt665x infrastructure it is important that vt6655 is also not using this code. (Patch already provided) vt6655 on mini PCI Module is using rf_type: RF_AIROHA (2.4GHz only) Philipp Hortmann (5): staging: vt6656: Remove unused rf_type in channel.c staging: vt6656: Remove unused rf_type in baseband.c staging: vt6656: Remove unused rf_type in rf.c; top level staging: vt6656: Remove unused rf_type in rf.c; unused variables staging: vt6656: Remove unused rf_type in card.c drivers/staging/vt6656/baseband.c | 16 +- drivers/staging/vt6656/card.c | 16 -- drivers/staging/vt6656/channel.c | 96 +------ drivers/staging/vt6656/rf.c | 413 +----------------------------- 4 files changed, 10 insertions(+), 531 deletions(-) -- 2.25.1
