From 0fcb5c76ca71afbef6c18d0710f2d4557b1d216a Mon Sep 17 00:00:00 2001 From: Richard Cochran Date: Sun, 29 Mar 2015 23:12:06 +0200 Subject: [PATCH] ptp: sfc: convert to the 64 bit get/set time methods. This patch changes the driver to use the newer API. Depending on how the hardware represents a time value, this driver may or may not yet be ready for the year 2038. Compile tested only.
