In 'poll_partial_rec_async' a uninitialized char variable 'token' with *garbage* value is used for write/read instruction to synchronize between threads via a pipe.

Initialize 'token' to '\0' to prevent write/read of garbage value.
I'm not opposed to making the compiler happy, but in this case "garbage" is completely fine, we don't care about the value.
So I think the subject and the commit message should talk about "silencing a compiler warning" rather than "fixing use of garbage value".
And your patch should indicate the target tree in the subject (here, with [PATCH net-next]), see https://www.kernel.org/doc/html/next/process/maintainer-netdev.html
