And *because* the name is visible in /proc/interrupts, it has become
an ABI, and cannot be changed anymore.

We had the exact same issue with Tegra this merge window as I
accidentally changed "Tegra" to "tegra", resulting in userspace
programs failing find stuff in /proc/interrupts.

Please keep the name as is, no matter how ugly it is.

Thanks,
