[PATCH v1 2/2] lib/uuid.c: use correct offset in uuid parser

From: Andy Shevchenko
Date: Mon May 30 2016 - 10:40:51 EST


From: BjÃrn Mork <bjorn@xxxxxxx>

Use '+ 0' and '+ 1' as offsets, like they were intended, instead
of adding to the result.

Fixes: 2b1b0d66704a ("lib/uuid.c: introduce a few more generic helpers")
