commitfe49aae0fcupstream. The match pattern for a optional trailing comma in the list of generics is erroneously repeated in the code block resulting in following error: | error: attempted to repeat an expression containing no syntax variables matched as repeating at this depth | --> rust/kernel/init.rs:301:73 | | | 301 | ::pin_init::try_pin_init!($(&$this in)? $t $(::<$($generics),* $(,)?>)? { | | ^^^ Remove "$(,)?" from all code blocks in the try_init! and try_pin_init! definitions.
