[PATCH] ASoC: SOF: ipc: Remove redundant error check from sof_ipc_tx_message_unlocked
If the snd_sof_dsp_send_msg() failed then we have already returned from sof_ipc_tx_message_unlocked() with the error message.
There is no need to check if ret is really 0 after this and we can return directly the return value from tx_wait_done()
At the same time make the remaining checks for error (ret) to match.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
