[alsa-devel] [PATCH] ASoC: intel: Don't print FW version repeatedly
Intel SST driver spews an info message "FW Versoin xxxx" at each time the device gets initialized. Since it's triggered at each PM (or even runtime PM), it appears so ofetn, and rather becomes annoying than useful.
This patch suppresses the superfluous messages by checking the currently loaded FW version with the previously loaded one.

You are if someone upgrades their userspace.

Right. If we want to keep the old one consistently, you should cache the firmware instead of doing request_firmware at each time.

Ah great thanks for reminding, we actually do that, so we don't load from userspace all the time. That was done to get good latency and avoid 50ms ish time it used to load the firmware.
see sst_cache_and_parse_fw() so dev_info_once() would suffice here

OK, I'll respin the patch with it.

Ah yes thats a good point indeed, so:

Thanks
The patch
ASoC: intel: Don't print FW version repeatedly
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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
