| |
'allegro_regmap_config' and 'allegro_sram_config' are not modified in this diver and are only used as a const struct regmap_config.
Constifying these structures moves some data to a read-only section, so increase overall security.
On a x86_64, with allmodconfig: Before: text data bss dec hex filename 79587 3706 116 83409 145d1 drivers/media/platform/allegro-dvt/allegro-core.o
After: text data bss dec hex filename 80219 3066 116 83401 145c9 drivers/media/platform/allegro-dvt/allegro-core.o
