Merge series "ASoC: da7219: Reorganise device/codec level probe/remove" from Adam Thomson <Adam.Thomson.Opensource@diasemi.com>:

Browse Source 
This patch set reorganises and fixes device and codec level probe/remove
handling within the driver, to allow clean probe and remove at the codec level.

This set relates to an issue raised by Yong Zhi where a codec level re-probe
would fail due to clks still being registered from the previous instantiation.
In addition some improvements around regulator handling and soft reset have
also been included.

Adam Thomson (3):
  ASoC: da7219: Move required devm_* allocations to device level code
  ASoC: da7219: Move soft reset handling to codec level probe
  ASoC: da7219: Fix clock handling around codec level probe
