Subject: [PATCH] tty: serial: constify uart_ops structures
Declare uart_ops structures as const as they are only stored in the ops
field of an uart_port structure. This field is of type const, so
uart_ops structures having this property can be made const too.
File size details before and after patching.
First line of every .o file shows the file size before patching
and second line shows the size after patching.
