From: Thomas Weißschuh Date: Sun, 22 Dec 2024 20:00:43 +0000 (+0100) Subject: Input: goodix-berlin - constify 'struct bin_attribute' X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=f9c883f0df2765c0cb1db3c306a36787ccb2055a;p=users%2Fdwmw2%2Flinux.git Input: goodix-berlin - 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.
