From 881321b6ed9e983ad733268404245fcf0be0b23c Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Fri, 18 Sep 2020 13:57:51 +0300 Subject: [PATCH] net: mscc: ocelot: make ocelot_init_timestamp take a const struct ptp_clock_info It is a good measure to ensure correctness if the structures that are meant to remain constant are only processed by functions that thake constant arguments.
