Subject: [PATCH] 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.
