[PATCH] ASoC: codecs: tlv320adc3xxx: Wrap adc3xxx_i2c_remove() in __exit_p()

[Geert Uytterhoeven]

If CONFIG_SND_SOC_TLV320ADC3XXX=y:

    `.exit.text' referenced in section `.data' of sound/soc/codecs/tlv320adc3xxx.o: defined in discarded section `.exit.text' of sound/soc/codecs/tlv320adc3xxx.o

Fix this by wrapping the adc3xxx_i2c_remove() pointer in __exit_p().

Why does this driver need this but most others don't?

Because most drivers don't annotate .remove() functions with __exit?
An alternative would be to drop the __exit annotation, at the expense
of a slightly larger kernel in the built-in case.

[1/1] ASoC: codecs: tlv320adc3xxx: Wrap adc3xxx_i2c_remove() in __exit_p()
      commit: 4e8ff35878685291978b93543d6b9e9290be770a

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
