From e7f1935c11269bc53cd52425b1025657adddb839 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 25 Jul 2013 21:45:17 +0200 Subject: wireless: make TU conversion macros available A few places in the code (mac80211 and iwlmvm) use the same TU_TO_JIFFIES() macro and could use TU_TO_EXP_TIME() that mac80211 has. Make these available to everyone and use them.
