This patch causes that the sound can not work normally on OMAP_L138.
Can you describe "can not work normally"? Does that mean simply does
not work, or works with pops & clicks etc.?
Just to clarify... how did you isolate it to this patch.
If you revert just this patch on current davinci git, do you have
working sound as you expect again?
Below is the test result:
$/root> aplay audiodump.wav
Playing WAVE 'audiodump.wav' : Signed 16 bit Little Endian, Rate 44100
Hz, Stereo
aplay: pcm_write:1269: write error: Input/output error
$/root>
After revert it, the audio works fine.
