The patch subject isn't entirely accurate here; this patch isn't just
about fixing clock entries.

Here, can't we just use the existing device names in the clock files...

So we can completely drop the changes to these two files:

> diff --git a/arch/arm/mach-tegra/tegra20_clocks_data.c b/arch/arm/mach-tegra/tegra20_clocks_data.c
> diff --git a/arch/arm/mach-tegra/tegra30_clocks_data.c b/arch/arm/mach-tegra/tegra30_clocks_data.c

The device names will hopefully be irrelevant once we're able to use
DT-based clock lookups.
