Subject: rust: add `pin-init` as a dependency to `bindings` and `uapi`
X-Git-Tag: v6.18-rc1~174^2~31
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=3c847e17225aa9481fc3f6c948f5c718dea526f1;p=thirdparty%2Flinux.git

rust: add `pin-init` as a dependency to `bindings` and `uapi`

This allows `bindings` and `uapi` to implement `Zeroable` and use other
items from pin-init.
