Subject: [PATCH v2 2/3] rust: remove `#[allow(clippy::unnecessary_cast)]`
Date: Fri, 27 Jun 2025 09:53:19 +0300 [thread overview]
Message-ID: <20250627065320.9315-3-work@onurozkan.dev> (raw)
In-Reply-To: <20250627065320.9315-1-work@onurozkan.dev>
This isn't needed anymore since `kernel::ffi::c_int` type
is always `i32` which differs from `err` (isize).
