ASoC: stm: stm32_i2s: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

ASoC: Use of_property_present() for testing DT property presence
It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

ASoC: stm32: i2s: remove irqf_oneshot flag
The IRQF_ONESHOT flag allows to ensure that the interrupt is not
unmasked after the hard interrupt context handler has been executed
and the thread has been woken. The interrupt line is unmasked after
the thread handler function has been executed.

The STM32 I2S driver does not implement a threaded IRQ handler.
So, the IRQF_ONESHOT flag is not useful in I2S driver.
Remove this flag to allow the interrupt routine to be managed
as a thread in RT mode.

ASoC: stm: Fix PM disable depth imbalance in stm32_i2s_probe
The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to

olivier moysan e7cc49b8ad ASoC: stm32: Add full duplex support to i2s
This patch allows to use i2s interface either as single
audio path (rx or tx), or bidirectional audio path.
This patch is added separately, as the driver does not
follow recommended use of the interface, to support this
configuration.
