[alsa-devel] Applied "ASoC: au1x: psc-i2s: constify dev_pm_ops structure" to the asoc tree
by Mark Brown 17 Jul '17

17 Jul '17

The patch ASoC: au1x: psc-i2s: constify dev_pm_ops structure 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 90982dcdda4f0163bc5e53f49301e155c2cd8547 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R.

[alsa-devel] [PATCH] ASoC: tegra: constify snd_soc_dai_ops structure
by Gustavo A. R. Silva 17 Jul '17

17 Jul '17

This structure is only stored in the ops field of a snd_soc_dai_driver structure. That field is declared const, so snd_soc_dai_ops structures that have this property can be declared as const also.
