Subject: [PATCH 1/8] rust: io: register: dispatch fixed array shortcut internally
Date: Tue, 21 Jul 2026 04:00:10 -0700 [thread overview]
Message-ID: <20260721-registers_fix-v1-1-3711b2317e1f@nvidia.com> (raw)
In-Reply-To: <20260721-registers_fix-v1-0-3711b2317e1f@nvidia.com>
The contiguous fixed-register-array shortcut redispatches an already
normalized declaration through the public register! entry point. This is
unneeded - the public rule should only be invoked by users.
Dispatch directly to the appropriate internal @reg rule instead.
