Description
Custom syntax in macros should be as similar to normal Rust syntax as possible in order to make them simpler to use. For example, when they use the struct initializer syntax Struct { foo: value, bar: other_value } they should allow both omitting and using a trailing comma. The current module! macro doesn't do this, so implement that.
Also any other macros in the macros crate should be adjusted in separate patches if they don't follow this principle
This requires submitting a proper patch to the LKML and the Rust for Linux mailing list. Please recall to test your changes (including generating the documentation if changed, running the Rust doctests if changed, etc.), to use a proper title for the commit, to sign your commit under the Developer's Certificate of Origin and to add a Suggested-by: tag, and a Link: tag to this issue. Please see https://docs.kernel.org/process/submitting-patches.html and https://rust-for-linux.com/contributing for details.
