From: Christophe JAILLET Date: Sun, 25 May 2025 09:21:24 +0000 (+0200) Subject: cxgb4: Constify struct thermal_zone_device_ops X-Git-Tag: v6.16-rc1~132^2~13 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=08f8bad0255c7319f4ffe53d0f0eab50fa2cb5e9;p=thirdparty%2Flinux.git cxgb4: Constify struct thermal_zone_device_ops 'struct thermal_zone_device_ops' are not modified in this driver. Constifying these structures moves some data to a read-only section, so increases overall security, especially when the structure holds some function pointers.
