Subject: [PATCH v1 10/20] cxl/region: Remove __construct_region()
Date: Tue, 15 Jul 2025 21:11:33 +0200 [thread overview]
Message-ID: <20250715191143.1023512-11-rrichter@amd.com> (raw)
In-Reply-To: <20250715191143.1023512-1-rrichter@amd.com>
There is nothing left the function does in addition to
construct_region(). Remove __construct_region() entirely.
