Warning from running nightly clippy on default repo

[Yung-Beef]

Per the 1.1 setup page there should be no warnings or errors from running cargo +nightly clippy however I am getting:

warning: unreachable pattern
  --> src/lib.rs:29:12
   |
29 |     #[pallet::call]
   |               ^^^^ matches no values because `polkadot_sdk_frame::deps::frame_support::Never` is uninhabited

   = note: to learn more about uninhabited types, see https://doc.rust-lang.org/nomicon/exotic-sizes.html#empty-types
   = note: `#[warn(unreachable_patterns)]` on by default

warning: `pallet-kitties` (lib) generated 1 warning

Everything passes for me:

Let's share versions?

➜  substrate-collectables-workshop git:(master) cargo +nightly clippy --version
clippy 0.1.82 (176e5452 2024-08-04)
➜  substrate-collectables-workshop git:(master) cargo clippy --version 
clippy 0.1.80 (05147895 2024-07-21)

No idea about a check script but here's what I get for those 2 commands

➜  substrate-collectables-workshop git:(master) cargo +nightly clippy --version
clippy 0.1.82 (8d6b88b 2024-09-11)
➜  substrate-collectables-workshop git:(master) cargo clippy --version 
clippy 0.1.81 (eeb90cd 2024-09-04)

I'm running it after git clone https://github.com/shawntabrizi/substrate-collectables-workshop/ -b starting-template --single-branch per the setup page, so I don't have the script or the steps folder.

@Yung-Beef okay i can reproduce. let me see what i can do, the error is coming from Polkadot SDK unfortunately

[shawntabrizi]

For now, please feel free to move on. I will try to get it fixed:
