Subject: [PATCH net-next v2] net: phy: qt2025: simplify Result<()> in probe
 return

From: Manas <manas18244@...td.ac.in>

probe returns a `Result<()>` type, which can be simplified as `Result`,
due to default type parameters being unit `()` and `Error` types. This
maintains a consistent usage of `Result` throughout codebase.
