Hi everyone!
This series is part of the set of dependencies for the drm/asahi Apple M1/M2 GPU driver.
It adds a bunch of missing wrappers in kernel::error, which are useful to convert to/from kernel error codes. Since these will be used by many abstractions coming up soon, I think it makes sense to merge them as soon as possible instead of bundling them with the first user. Hence, they have allow() tags to silence dead code warnings. These can be removed as soon as the first user is in the kernel crate.
Getting this in first allows the subsequent abstractions to be merged in any order, so we don't have to worry about piecewise rebasing and fixing conflicts in the Error wrappers. See [1] for a complete tree with the DRM abstractions and all other miscellaneous work-in-progress prerequisites rebased on top of mainline.
Most of these have been extracted from the rust-for-linux/rust branch, with author attribution to the first/primary author and Co-developed-by: for everyone else who touched the code.
Attribution changes: - One of the patches had Miguel's old email in the tags, updated that per his request. - Wedson's email changed from @google.com to @gmail.com (I understand this is the current one).
Sven: There is one patch from you in this series, do you want to send it yourself directly? I understand Wedson and Miguel are okay with me sending stuff on their behalf.
