[PATCH 4.14 035/189] ASoC: msm8916-wcd-analog: use threaded context for mbhc events

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

[ Upstream commit a8419a0cd98ddf628a9e38a92110af7cc650dde7 ]

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')
