[alsa-devel] [PATCH 6/7] ASoC: TWL4030: Correct the ARXR2_APGA_CTL chip default

[Peter Ujfalusi]

It seams at least on twl5031 that the ARXR2_APGA_CTL register
does not have the same default value as it is written in
the TRM.
Since the codec part of the PM chip has not been actually
changed according to TI, assuming, that all version has
the same problem, so writing there the TRM value.
