Subject: [PATCH] ASoC: msm8916-wcd-analog: use threaded context for mbhc events

From: Srinivas Kandagatla <srinivas.kandagatla@...aro.org>

As snd_soc_jack_report() can sleep, move handling of mbhc events to a
thread context rather than in interrupt context.

Fixes: de66b3455023 ('ASoC: codecs: msm8916-wcd-analog: add MBHC support')
Reported-by: Bjorn Andersson <bjorn.andersson@...aro.org>
