We found an corner case in RT5640 codec driver which schedules jack work
after system suspend as IRQ was enabled. Due to this, hitting the error
as register access happening after suspend as jack worker thread getting
scheduled in irq handler. The patch disables the irq during the suspend
to prevent the corner case happening.

      commit: 5fabcc90e79b460d72df582b31854f6018695965

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
