'struct drm_info_list' is not modified in this driver.
Constifying this structure moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename
1411 320 0 1731 6c3 drivers/gpu/drm/armada/armada_debugfs.o
After:
=====
text data bss dec hex filename
1683 48 0 1731 6c3 drivers/gpu/drm/armada/armada_debugfs.o
