[alsa-devel] [PATCH v2 0/2] ASoC: Give prettier longname based on DMI
Hi,
this is the revised patchset to set the card longname based on DMI so that a unique UCM profile can be picked up.
v1->v2: Fix the missnig NULL argument in the function call

For systems without DMI, it makes no sense to have the code.

Since recently UCM can pick up a configuration specific to the board via card longname field, and we introduced a helper function snd_soc_set_dmi_name() for that. So far, it was used only in one place (sound/soc/intel/boards/broadwell.c), but it should be more widely applied.
This patch puts a big hammer for that: it lets snd_soc_register_card() calling snd_soc_set_dmi_name() unconditionally, so that all x86 devices get the better longname string. This would have no impact for other systems without DMI support, as snd_soc_set_dmi_name() is no-op on them.

The patch
ASoC: Call snd_soc_set_dmi_name() unconditionally
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
