ASoC: fsl: fsl_ssi: Fix simultaneous capture and playback
When doing simultaneous capture and playback on a mx6 board we get the following
error:
$ arecord -f cd | aplay -f cd
imx-sgtl5000 sound.13: set sample size in capture stream first
fsl-ssi-dai 2028000.ssi: ASoC: can't open interface 2028000.ssi: -11
ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_
open) unable to open slave
aplay: main:660: audio open error: Device or resource busy
Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
The 'arecord -f cd | aplay -f cd' always trigger cause the
'if (!first_runtime->sample_bits)' block to be true which returns an error.
Adjust the logic inside fsl_ssi_startup(), so that we do not always hit the
error when playing 'arecord | aplay' line for the first time.
