[PATCH net-next 1/2] mptcp: Constify mptcp_pm_ops

From: Rikard Falkeborn
Date: Sun Oct 04 2020 - 17:58:24 EST


The only usages of mptcp_pm_ops is to assign its address to the ops field
of the genl_family struct, which is a const pointer, and applying
ARRAY_SIZE() on it. Make it const to allow the compiler to put it in
read-only memory.
