Building this file with clang leads to a an unreachable code path

Change the unreachable() into an error return that can be
handled if it ever happens, rather than silently crashing
the kernel.

Applied to

Thanks!

[1/1] spi: rockchip: avoid objtool warning
      commit: d86e880f7a7c5b64a650146a1353f98750863f21

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
