tty: mxser: constify pci_device_id.
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 before: text data bss dec hex filename 20253 1184 19904 41341 a17d drivers/tty/mxser.o File size After adding 'const': text data bss dec hex filename 21117 300 19904 41341 a17d drivers/tty/mxser.o Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
