Subject: staging: dgnc: Remove casting the return value which is a void pointer
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0e4f66b448c650851b1e16cae08f9700e403c341;p=openwrt%2Fstaging%2Fblogic.git

staging: dgnc: Remove casting the return value which is a void pointer

Casting the return value which is a void pointer is redundant.
The conversion from void pointer to any other pointer type is
guaranteed by the C programming language.
