[PATCH 03/11] rtlwifi: rtl8821ae: constify pci_device_id.

Show all headers | View raw

pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

File size After adding 'const':
