Thank you. This is a new warning to me, apparently this case wasn't previously tested by kernel build bot.

Perhaps this should fix it:

diff --git a/drivers/memory/tegra/Kconfig b/drivers/memory/tegra/Kconfig

- depends on ARCH_TEGRA_210_SOC

Thierry, please squash this change into the original patch if it looks good to you.
