Subject: hwrng: mxc-rnga - Remove uneeded initialization
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c09e2cc69441ef5d99d31aa83f7d2b6239e5b9a7;p=openwrt%2Fstaging%2Fblogic.git

hwrng: mxc-rnga - Remove uneeded initialization

There is no need to pre-initialize variable 'err' as this
initial value will be overwritten later on.
