Subject: [media] radio-bcm2048: fix signal of value
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=356ba0213dca4dd68906bb315f8c7a46e81510ea;p=openwrt%2Fstaging%2Fblogic.git

[media] radio-bcm2048: fix signal of value

As value can be initialized with a value lower than zero, change it
to int, to avoid those warnings:
