[PATCH v5 02/17] ASoC: fsl_ssi: Keep ssi->i2s_net updated

2018-01-16 Thread Nicolin Chen
The hw_params() overwrites i2s_net settings for special cases like
mono-channel support, however, it doesn't update ssi->i2s_net as
set_dai_fmt() does.

This patch removes the local i2s_net variable and directly updates
ssi->i2s_net in the hw_params() so that the driver can simply look
up the ssi->i2s_net instead of reading the register.
