Subject: [PATCH v2 1/3] x86/mce: Use __DEVICE_ATTR() macro to initialize dev_ext_attribute
Date: Mon, 07 Sep 2026 07:45:01 +0200	[thread overview]
Message-ID: <20260907-sysfs-const-attr-dev_ext_attr-v2-1-bf53afe57071@weissschuh.net> (raw)
In-Reply-To: <20260907-sysfs-const-attr-dev_ext_attr-v2-0-bf53afe57071@weissschuh.net>

The upcoming constification of the device_show_int() and
device_show_bool() signatures requires the users to handle the
transition automatically.

Switch to the __DEVICE_ATTR() macro which can do this.
