mailbox: tegra xusb: undefined MFD_TEGRA_XUSB

Hi Andrew,

your commit b1f10002b00a ("mailbox: Add NVIDIA Tegra XUSB mailbox
driver") is in today's linux-next tree (i.e., next-20150513) and it
adds the following lines:

+ tristate "NVIDIA Tegra XUSB Mailbox"
+ depends on MFD_TEGRA_XUSB

At the current state, the dependency is always false since the option
MFD_TEGRA_XUSB is not defined in Kconfig, and the added driver cannot
be compiled.

Is there a patch queued somewhere to add this missing option?

I detected the issue with undertaker-checkpatch [1, 2] running on a
bot in Erlangen [3] to make daily checks of commits in linux-next for
#ifdef related bugs.

Kind regards,
