No patch description?

Something isn't quite right with the device registration here. If U-Boot
starts with stdin=serial, and then I "setenv stdin
serial,tegra-nvec-kbc", then I can't use the keyboard. However, if I
save the environment and reset, then nvec input works. Similarly, it
gets confused if I remove and re-add tegra-nvec-kbc to $stdin.

I've also observed quite a stuck keys, hangs, and failed requests:
ERROR: nvec failed to perform request
at .../drivers/i2c/tegra_nvec.c:166/nvec_do_request()

But when it works, it's nice:-)
