Subject: Staging: dgnc: Remove redundant parentheses
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=64e784c4574d9015eee0b97cbf66c2eafcd38feb;p=openwrt%2Fstaging%2Fblogic.git

Staging: dgnc: Remove redundant parentheses

This patch removes the redundant parentheses inorder to make code
simplified. While doing this, the precedence order of the operation
is taken into consideration to keep the logic of the code intact.
