From: Thomas Weißschuh Date: Mon, 16 Dec 2024 11:30:09 +0000 (+0100) Subject: net: phy: ks8995: constify 'struct bin_attribute' X-Git-Tag: v6.14-rc1~162^2~200^2~1 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2d7b422fa7952e3f15fc0912b12530af1d265193;p=thirdparty%2Flinux.git net: phy: ks8995: constify 'struct bin_attribute' The sysfs core now allows instances of 'struct bin_attribute' to be moved into read-only memory. Make use of that to protect them against accidental or malicious modifications.
