[alsa-devel] ASoC: pxa2xx-i2s

i2s replay is not being enabled properly on occasion on my pxa270
board. Current code is touching SACR1 in hw_params which I believe is
not correct. That should be configured in trigger before enabling i2s.
Record is not disabled for playback mode. Any invalid data in the
transmit fifo causes deadlock and replay is being disabled.
I have been able to reproduce it in kernel 2.6.26 as well as Linus' git
tree using speaker-test. (repeatedly starting and stopping). I've
verified that this fix prevents (at least) this condition.
Please review this patch and let me know if there is anything I have
