From 494fd076ea7bde10142ad427d7ce9c32b238b6db Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Wed, 3 Jan 2018 10:43:34 +0530 Subject: [PATCH] ata_piix: constify pci_bits pci_bits are not supposed to change at runtime. Functions pci_test_config_bits() working with const 'struct pci_bits'. So mark the non-const structs as const.
