From 057d32f03d0d5425b3e089d98712d6cc962b705f Mon Sep 17 00:00:00 2001 From: Bing Zhao Date: Fri, 20 Jun 2014 17:07:42 -0700 Subject: [PATCH] Revert "mwifiex: Use the proper interfaces" This reverts commit a82fc3b4a2bceb7c6587249cb690342eb5065979. Thomas corrected me on that I misunderstood Johannes' comment for net_timedelta() and the ktime_get_real() usage inside __net_timestamp(). Cc: Thomas Gleixner Cc: Johannes Berg Cc: John W.
