tty: serial: jsm: 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 2442 1088 8 3538 dd2 tty/serial/jsm/jsm_driver.o File size After adding 'const': text data bss dec hex filename 3082 448 8 3538 dd2 tty/serial/jsm/jsm_driver.o Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
