Subject: onewire_parser: Fix memory leak when retrying OWNET_read()
X-Git-Url: http://git.itanic.dy.fi/?p=rrdd;a=commitdiff_plain;h=0d9d53dd15194d607f81a82db97403c37fb2f126

onewire_parser: Fix memory leak when retrying OWNET_read()

If it happens that read fails for any reason and the code retries
reading, the previous read buffer is not freed properly. This causes a
minor (26 byte) memory leak on each retry. Add a free() call to avoid
the leak.
