[ Upstream commit 41c721fc093938745d116c3a21326a0ee03bb491 ]
Some machines with tegra_qspi_combined_seq_xfer hardware issues generate excessive kernel warnings, severely polluting the logs:
dmesg | grep -i "WARNING:.*tegra_qspi_transfer_one_message" | wc -l 94451
This patch replaces WARN_ON with WARN_ON_ONCE for timeout conditions to reduce log spam. The subsequent error message still prints on each occurrence, providing sufficient information about the failure, while the stack trace is only needed once for debugging purposes.
