#1531472 — [PATCH 5/5] Input: arizona-haptics - Use SoC component pin control functions

The name of a codec pin can have an optional prefix string, which is
defined by the SoC machine driver. The snd_soc_dapm_x_pin functions
take the fully-specified name including the prefix and so the existing
code would fail to find the pin if the audio machine driver had added
a prefix.

Switch to using the snd_soc_component_x_pin equivalent functions that
take a specified SoC component and automatically add the name prefix to
the provided pin name.

If ASOC folks are fine with this then I am otto. Please merge with the rest of
Arizona changes.

#1534470 — Applied "Input: arizona-haptics - Use SoC component pin control functions" to the asoc tree

The patch

   Input: arizona-haptics - Use SoC component pin control functions

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

Subject: [PATCH] Input: arizona-haptics - Use SoC component pin control
 functions

The name of a codec pin can have an optional prefix string, which is
defined by the SoC machine driver. The snd_soc_dapm_x_pin functions
take the fully-specified name including the prefix and so the existing
code would fail to find the pin if the audio machine driver had added
a prefix.

Switch to using the snd_soc_component_x_pin equivalent functions that
take a specified SoC component and automatically add the name prefix to
the provided pin name.
