From 898918d67399bb73d6af1503038623a610d294a2 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Thomas=20Wei=C3=9Fschuh?= Date: Sun, 15 Dec 2024 16:21:24 +0100 Subject: [PATCH] iio: imu: bno055: constify 'struct bin_attribute' MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
