Description

Currently, the GPU struct specifies the type of its `major` and `minor` fields as `dev_t`, which is actually a concatenation of both the major and minor device numbers accessible through the `major()` and `minor()` macros. These macros return an `unsigned int` when handed a `dev_t`, so it makes sense for these fields to be of that type instead.
