Subject: perf/hw_breakpoint: Remove superfluous bp->attr.disabled = 0
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=cb45302d7c5e20f0c0598cdbd7753fa44daceb2a;p=openwrt%2Fstaging%2Fblogic.git

perf/hw_breakpoint: Remove superfluous bp->attr.disabled = 0

Once the breakpoint was succesfully modified, the attr->disabled value
is in bp->attr.disabled. So there's no reason to set it again, removing
that.
