tegra_vi_channels_alloc() can primarily fail for two reasons: 1. "ports" node not found 2. port_num > vi->soc->vi_max_channels Case 1 prints nothing, case 2 has a dev_err(). The caller [tegra_vi_init()] has a generic dev_err() on any failure. This mean that in case 2 we print two messages, and in case 1 we only print a generic message. Remove the generic message and add a specific message when case 1 happens, so that we always have one specific message without even increasing the number of dev_dbg*() calls.
