[alsa-devel] [PATCH 1/2] ASoC: tlv320aic32x4: Add support for tlv320aic32x6

[alsa-devel] Applied "ASoC: rsnd: remove unnecessary static in rsnd_ssiu_probe()" to the asoc tree
by Mark Brown 17 Jul '17

17 Jul '17

The patch ASoC: rsnd: remove unnecessary static in rsnd_ssiu_probe() 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 >From 32e1b60d8f91be932c4a624d4153224895b65ec7 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R.

Instead, we may introduce configure option to explicitly control the usage of wordexp(), and add your extension to the fallback code, for example.
