[PATCH 0/2] ASoC: qcom: sdw: fix memory leak

[Srinivas Kandagatla <srinivas.kandagatla@oss.qualcomm.com>]

While testing for memoryleaks on T14s, it was found that the
struct sdw_stream_runtime was leaking very frequently.

For some reason we endedup allocating sdw_stream_runtime for every cpu dai,
this has two issues.
    1. we never set snd_soc_dai_set_stream for non soundwire dai, which
       means there is no way that we can free this, resulting in memory leak
    2. startup and shutdown callbacks can be called without
       hw_params callback called. This combination results in memory leak
    because machine driver sruntime array pointer is only set in hw_params
    callback.
    

This patch series fix the issue, and while we are at it, it also remove
some redundant code from machine drivers.

Thanks,
Srini
