[PATCH v0 8/9] media: qcom: camss: Fix set CSI2_RX_CFG1_VC_MODE when VC is greater than 3
From: Bryan O'Donoghue
Date: Mon Aug 14 2023 - 10:11:14 EST
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")
