Selecting a symbol with additional dependencies requires
adding the same dependency here:

WARNING: unmet direct dependencies detected for MUX_MMIO
  Depends on [n]: MULTIPLEXER [=y] && OF [=n]
  Selected by [y]:
  - SPI_DW_BT1 [=y] && SPI [=y] && SPI_MASTER [=y] && SPI_DESIGNWARE [=y] && (MIPS_BAIKAL_T1 || COMPILE_TEST [=y])

Drop the 'select' here to avoid the problem. Anyone using
the dw-bt1 SPI driver should make sure they include the
mux driver as well now.

Fixes: 7218838109fe ("spi: dw-bt1: Fix undefined devm_mux_control_get symbol")
Fixes: abf00907538e ("spi: dw: Add Baikal-T1 SPI Controller glue driver")

Thanks!

[1/1] spi: dw_bt1: fix MUX_MMIO dependencies
      commit: d4bde04318c0d33705e9a77d4c7df72f262011e0

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
