[PATCH] ASoC: fix unmet dependency on GPIOLIB

[PATCH] ASoC: fix unmet dependency on GPIOLIB

[Julian Braha]

When SND_SOC_SC7180 or SND_SOC_STORM is selected,
and GPIOLIB is not selected, Kbuild gives the following
warning:

WARNING: unmet direct dependencies detected for SND_SOC_MAX98357A
  Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && GPIOLIB [=n]
  Selected by [y]:
  - SND_SOC_STORM [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_QCOM [=y]
  - SND_SOC_SC7180 [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_QCOM [=y] && I2C [=y]

This is because SND_SOC_MAX98357A is selected
by SND_SOC_STORM and SND_SOC_SC7180, but
these config options do not select or depend on
GPIOLIB, despite SND_SOC_MAX98357A depending on
GPIOLIB.

These unmet dependency bugs were detected by Kismet,
a static analysis tool for Kconfig. Please advise if this
is not the appropriate solution.

[1/1] ASoC: fix unmet dependency on GPIOLIB
      commit: 6cace797f1a8d54ecb42a3d327cbc0b231114ed0

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
