Subject: [PATCH v4 5/6] rust: remove `#[allow(clippy::unnecessary_cast)]`
Date: Tue, 1 Jul 2025 08:35:56 +0300 [thread overview]
Message-ID: <20250701053557.20859-6-work@onurozkan.dev> (raw)
In-Reply-To: <20250701053557.20859-1-work@onurozkan.dev>
This isn't needed anymore since `kernel::ffi::c_int` type
is always `i32` which differs from `err` (isize).
