[PATCH 03/11] scsi: arcmsr: Constify 'struct bin_attribute'

Thomas Weißschuh linux at weissschuh.net
Mon Dec 16 22:29:10 AEDT 2024


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.
