Subject: [PATCH] staging: dgnc: dgnc_cls.c: Replaced udelay by usleep_range
Date: Tue, 24 Nov 2015 23:01:13 +0530 [thread overview]
Message-ID: <1448386273-10699-1-git-send-email-jitendra.khasdev@hotwaxsystems.com> (raw)
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.
