tty: serial: constify dev_pm_ops structures
Declare dev_pm_ops structures as const as they are only stored in the pm field of a device_driver structure. This field is of type const, so dev_pm_ops structures having similar properties can be declared const too. Size details after cross compiling the .o file for blackfin architecture. File size before: text data bss dec hex filename 3572 320 16 3908 f44 tty/serial/bfin_sport_uart.o File size after: text data bss dec hex filename 3664 228 16 3908 f44 tty/serial/bfin_sport_uart.o Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
