From 90241fb9b55a36edd9dafb8de679f66836e84369 Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Fri, 7 Apr 2017 15:03:59 +0530 Subject: pwm: tegra: Use DIV_ROUND_CLOSEST_ULL() instead of local implementation Use macro DIV_ROUND_CLOSEST_ULL() for 64-bit division to closest one instead of implementing the same locally. This increase readability.
