  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.

      commit: 7c0f8f1462c9edeaa202a2cbea1bde0960434b09

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
