[alsa-devel] [PATCH] ASoC: sgtl5000: Allow the codec to work in slave mode

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at freescale.com>

When configuring sgtl5000 to work in slave mode the following error is seen:

root at freescale /$ aplay dtmf_mono_16b_48000.wav 
[   11.406460] random: nonblocking pool is initialized
[   11.600461] sgtl5000 1-000a: PLL not supported in slave mode
[   11.609052] sgtl5000 1-000a: ASoC: can't set sgtl5000 hw params: -22
ALSA lib pcm_direct.c:980:(snd1_pcm_direct_initialize_slave) unable to install hw params
ALSA lib pcm_dmix.c:1030:(snd_pcm_dmix_open) unable to initialize slave
aplay: main:660: audio open error: Invalid argument

Do not error out when sgtl5000_set_clock() reaches the default path for slave 
mode.

While at it, fix a typo in the comment.

Tested on a imx53-qsb configured as ssi in master and sgtl5000 as slave.
