[PATCH v2 0/2] ASoC: Give prettier longname based on DMI

[Takashi Iwai]

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

[PATCH v2 1/2] ASoC: Provide a dummy wrapper of snd_soc_set_dmi_name()

[Takashi Iwai]

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

[PATCH v2 2/2] ASoC: Call snd_soc_set_dmi_name() unconditionally

[Takashi Iwai]

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.

Applied "ASoC: Call snd_soc_set_dmi_name() unconditionally" to the asoc tree

[Mark Brown]

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
