Subject: pipe: fix failure to return error code on ->confirm()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e5953cbdff26f7cbae7eff30cd9b18c4e19b7594;p=openwrt%2Fstaging%2Fblogic.git

pipe: fix failure to return error code on ->confirm()

The arguments were transposed, we want to assign the error code to
'ret', which is being returned.
