Subject: [PATCH v2 3/6] module: sysfs: Drop 'struct module_sect_attr'
Date: Fri, 27 Dec 2024 14:23:22 +0100 [thread overview]
Message-ID: <20241227-sysfs-const-bin_attr-module-v2-3-e267275f0f37@weissschuh.net> (raw)
In-Reply-To: <20241227-sysfs-const-bin_attr-module-v2-0-e267275f0f37@weissschuh.net>
This is now an otherwise empty wrapper around a 'struct bin_attribute',
not providing any functionality. Remove it.
Signed-off-by: Thomas Weißschuh <linux@weissschuh.net>
