From 21ebcd1224d05c8673053e1e93ab9ec7ef3e0b84 Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Sun, 14 Jan 2007 15:29:07 +0100 Subject: [PATCH] firewire: mark some structs const Instances of struct file_operations and struct fw_card_driver can be qualified as "const". Ditto with struct fw_descriptor.data, struct fw_device_id, and predefined instances of struct fw_address_region, at least in the current implementation. Data qualified as const is placed into the .rodata section which won't be mixed with dirty data.
