Subject: [media] xc5000: properly report i2c write failures
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0a3dabb15ef9039188464647113398ed95400318;p=openwrt%2Fstaging%2Fblogic.git

[media] xc5000: properly report i2c write failures

The logic as written would *never* actually return an error condition,
since the loop would run until the counter hit zero but the check was
for a value less than zero.
