Something seems to be mangled with your quoting/new text here so it's a
bit unclear what you're saying here but if you're saying that this is
due to needing to call tegra_qspi_transfer_end() after updating the
length I'm not sure why - AFAICT that function doesn't reference the
transfer length at all, it just writes out a command to configure the
chip select? There's no issue with the message being finalised since
that happens in the caller.
