From c5268bbdbb441e1c497d59163872ddfba9bf67cf Mon Sep 17 00:00:00 2001 From: Julia Kreger Date: Thu, 4 Nov 2021 09:42:04 -0700 Subject: [PATCH] Fix UEFI record regex I accidently put colons on the test data and remembered taking the colon character out of the regex I was working on, but apparently left it in, and accounted for the active entry indicator flag which appears to have inconsistent support across vendors. The regex has been fixed, and a test added from a Lenovo SR650 which has some additional string entry data in the UEFI output which may separate entries.
