Subject: staging: dgnc: dgnc_cls.c: Replaced udelay by usleep_range
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6e411751f00faf00379f6aa94701ab360b068cff;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

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.
