Subject: [PATCH] tty: serial: Add const to struct uart_ops declarations

From: [email-masked] (Joe Perches)
Date: Sat, 04 Apr 2015 10:47:45 -0700

These structs can be const, so make them const.

Signed-off-by: Joe Perches <[email-masked]>

Done with:
sed -r -i -e 's/\bstruct\s+uart_ops\s+(\w+)\s*=\s*/const struct uart_ops \1 = /g' drivers/tty/serial/*.c

Compiled x86 only, not cross-compiled.  Untested.
