From 6e411751f00faf00379f6aa94701ab360b068cff Mon Sep 17 00:00:00 2001 From: Jitendra Kumar Khasdev Date: Tue, 24 Nov 2015 23:01:13 +0530 Subject: [PATCH] staging: dgnc: dgnc_cls.c: Replaced udelay by usleep_range This patch is to file dgnc_cls.c that fixes up udelay function by usleep_range. It is safe to use according to the following documentation Documentation/timers/timers-howto.txt. So that is why I have given an appropriate time range.
