Subject: onewire_parser: Increase glitch detection retry count to 4
X-Git-Url: http://git.itanic.dy.fi/?p=rrdd;a=commitdiff_plain;h=a12b785bb7b853742c1dc4e31afc6623e49ca1aa

onewire_parser: Increase glitch detection retry count to 4

In order to detect glitches properly, we might need to do more than
two reads, especially on noisy lines. Double the amount of reads we do
so that we have better chance of removing glitches from the data.
