From: Thomas Weißschuh Date: Tue, 7 Feb 2023 19:55:19 +0000 (+0000) Subject: cpuidle: sysfs: make kobj_type structures constant X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e898b07deb3ce801b21113979a05f4b3166c7cb3;p=linux.git cpuidle: sysfs: make kobj_type structures constant Since commit ee6d3dd4ed48 ("driver core: make kobj_type constant.") the driver core allows the usage of const struct kobj_type. Take advantage of this to constify the structure definitions to prevent modification at runtime. Signed-off-by: Thomas Weißschuh Signed-off-by: Rafael J.
