[PATCH v2 1/6] ASoC: SDCA: propagate sdw_slave_read_prop() failure in class_read_prop

[Srinivas Kandagatla]

sdw_slave_read_prop() can fail with -ENOMEM; propagate the return
instead of leaving slave->prop partially initialised.

[PATCH v2 2/6] ASoC: SDCA: drop pm_runtime reference on probe failure path

[Srinivas Kandagatla]

sdca_class_probe() takes an extra usage count with
pm_runtime_get_noresume() to keep the device powered on until the
deferred boot work has run. If devm_pm_runtime_enable() then fails,
that reference is never dropped.

Drop it on the error path.

[PATCH v2 3/6] ASoC: SDCA: re-enable IRQ on pm_runtime_force_suspend failure

[Srinivas Kandagatla]

The SoundWire IRQ was disabled before pm_runtime_force_suspend() but
never re-enabled when the force suspend failed, leaving the codec
unable to receive interrupts.
