[PATCH] tty: amba-pl011: constify vendor_data structures

From: Julia Lawall
Date: Fri Aug 11 2017 - 08:13:10 EST


These vendor_data structures are only stored in the vendor field of
the uart_amba_port structure, as defined in the same file, and this
field is declared as const. Thus the vendor_data structures can be
const too.

Done with the help of Coccinelle.

There are some other vendor_data structures in the same file, but
they are used in a different way.
