| |
Many of us, especially in the embedded computing world, think that "legacy bus" is a misnomer. It's not going away. What do root PCI buses connect to? At the root of the device tree there is a bus. This patch changes the name from legacy bus to platform bus. I'm hoping this change can be made even this late in the development cycle. It is a pretty small patch but I think that naming is very important.
