Subject: [PATCH 4/7] EDAC: Remove dynamic attributes from edac_device_alloc_ctl_info()
Date: Tue, 13 Feb 2024 12:20:48 +0100
Message-ID: <20240213112051.27715-5-jirislaby@kernel.org>
In-Reply-To: <20240213112051.27715-1-jirislaby@kernel.org>
References: <20240213112051.27715-1-jirislaby@kernel.org>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Dynamic attributes are not passed from any caller of
edac_device_alloc_ctl_info(). Drop this unused/untested functionality
completely.
