| Series | PCI: Constify 'struct bin_attribute' | expand |
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. The usage of read_new/write_new/bin_attrs_new is a transition mechanism and will be reverted after the transition is complete.
