From: Arnd Bergmann <arnd@arndb.de>

The sai driver now links against the SCMI code directly, causing a
link failure when that is in a loadable module:

aarch64-linux-ld: sound/soc/fsl/fsl_sai.o: in function `fsl_sai_probe':
fsl_sai.c:(.text+0x1fe4): undefined reference to `scmi_imx_misc_ctrl_set'

Move the dependency from SND_SOC_FSL_MQS to SND_SOC_FSL_SAI. The MQS
driver depends on the SAI one, so it still gets the same dependency
indirectly.

All other drivers that select the SAI symbol need the same dependency
in turn, though that could probably get replaced with a 'depends on
SND_SOC_FSL_SAI' to keep it simpler.

Thanks!

[1/1] ASoC: fsl_sai: add IMX_SCMI_MISC_DRV dependency
      commit: 742048f2e128c06d0ef89ffc334519cb8e991f66

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
