ASoC: cs42l43: Add shared IRQ flag for shutters

Commit Message

The microphone and speaker shutters on cs42l43 can be configured to
trigger from the same GPIO, in this case the current code returns an
error as we attempt to request two IRQ handlers for the same IRQ. Fix
this by always requesting the shutter IRQs with the IRQF_SHARED flag.

[1/1] ASoC: cs42l43: Add shared IRQ flag for shutters
      commit: c923e7759a29cf67aa4dda77b816263771380f86

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
