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
index 71bba2345bce..3f2fa7750118 100644

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