The P1022DS machine driver should be setting SND_SOC_DAIFMT_CBM_CFM, but since that value was zero, no one noticed. Commit 75d9ac46 ("ASoC: Allow DAI formats to be specified in the dai_link"), however, changed the value of SND_SOC_DAIFMT_CBM_CFM from zero to a non-zero value, which means that it now needs to be specifically set by the machine driver.

This results in randomly swapped left/right channels on either the record or the playback side, depending on which one was enabled first. The following patch fixes this by factoring out the bit field modifications in question to a separate function that pauses the engine temporarily, modifies the bits and kicks it off again afterwards. Appearantly, a transition of SSCR0_SSE syncs both directions properly. The patch has been rolled out to quite a number of devices over the last weeks and seems to fix the issue reliably.
