[alsa-devel] [PATCH] ASoC: Amstrad Delta: fix const related build error

[Janusz Krzysztofik]

The Amstrad Delta ASoC driver used to override the digital_mute() 
callback, expected to be not provided by the on-board CX20442 CODEC 
driver, with its own implementation. While this is still posssible when 
substituting the whole empty snd_soc_dai_driver.ops member (the CX20442 
case), replacing snd_soc_dai_ops.digital_mute only is no longer correct 
after the snd_soc_dai_driver.ops member has been constified, and results 
in build error.

Drop this actually not used code path in hope the CX20442 driver never 
provides its own snd_soc_dai_ops structure.

Created and tested against linux-2.6.38-rc2
