Subject: [PATCH v3 5/6] rust: miscdevice: set fops.owner from driver module pointer
Date: Mon, 22 Jun 2026 10:44:59 +0800 [thread overview]
Message-ID: <20260622-fix-fops-owner-v3-5-49d45cb37032@linux.dev> (raw)
In-Reply-To: <20260622-fix-fops-owner-v3-0-49d45cb37032@linux.dev>
Set the miscdevice fops owner field from the driver module pointer
via the `this_module::<T::OwnerModule>()` helper, instead of
defaulting to null.
