ALSA: compress: add flac decoder params

has been applied to the asoc tree at

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5

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.

From: Vinod Koul vkoul@kernel.org Date: Fri, 15 Nov 2019 15:57:03 +0530 Subject: [PATCH] ALSA: compress: add flac decoder params

The current design of sending codec parameters assumes that decoders will have parsers so they can parse the encoded stream for parameters and configure the decoder.

But this assumption may not be universally true and we know some DSPs which do not contain the parsers so additional parameters are required to be passed.

So add these parameters starting with FLAC decoder. The size of snd_codec_options is still 120 bytes after this change (due to this being a union)
