Hello, This patch series finishes the constification of struct drm_driver in the DRM core by avoiding modifications to the structure for legacy PCI drivers. This improves security by avoiding function pointers in writable memory. The change turned out to be fairly easy, with preparation in patch 1/3 that moves the only non-const field out of drm_driver, and patch 2/3 that finishes the constification in the DRM core. Patch 3/3 is a low-hanging fruit that constifies the structure in a few drivers. The remaining non-const drivers modify the structure internally to set the num_ioctls fields, and in a few cases, change the driver features. This will require a bit more work to fix these cases.
