[PATCH 2/2] l2tp: constify inet6_protocol structures

Show all headers | View raw

The inet6_protocol structure is only passed as the first argument to
inet6_add_protocol or inet6_del_protocol, both of which are declared as
const.  Thus the inet6_protocol structure itself can be const.

Also drop __read_mostly on the newly const structure.

Done with the help of Coccinelle.
