[PATCH] ASoC: tas2781: fix Kconfig dependencies

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The new driver has two modules that both get enabled for build testing
when all codecs are selected. The comlib part has an i2c dependency,
so this remains disabled on builds without i2c, but then the other
one fails to link:

ERROR: modpost: "tasdevice_dev_bulk_write" [sound/soc/codecs/snd-soc-tas2781-fmwlib.ko] undefined!
ERROR: modpost: "tasdevice_dev_update_bits" [sound/soc/codecs/snd-soc-tas2781-fmwlib.ko] undefined!
ERROR: modpost: "tasdevice_dev_bulk_read" [sound/soc/codecs/snd-soc-tas2781-fmwlib.ko] undefined!
ERROR: modpost: "tasdevice_dev_read" [sound/soc/codecs/snd-soc-tas2781-fmwlib.ko] undefined!
ERROR: modpost: "tasdevice_dev_write" [sound/soc/codecs/snd-soc-tas2781-fmwlib.ko] undefined!

There are many ways to address this, adding an explicit dependency seems
to be the clearest method that keeps the structure of the driver otherwise
unchanged.

      commit: fcb66ee8d16aa0f88efcc9cb41083c0412e9db8a

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
