Subject: media: qcom: camss: Fix set CSI2_RX_CFG1_VC_MODE when VC is greater than 3
From: Bryan O'Donoghue <bryan.odonoghue@xxxxxxxxxx>
commit e655d1ae9703286cef7fda8675cad62f649dc183 upstream.
VC_MODE = 0 implies a two bit VC address.
VC_MODE = 1 is required for VCs with a larger address than two bits.
Fixes: eebe6d00e9bf ("media: camss: Add support for CSID hardware version Titan 170")
