tty: mux: constify parisc_device_id
parisc_device_id are not supposed to change at runtime. All functions working with parisc_device_id provided by <asm/parisc-device.h> work with const parisc_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
