[PATCH] Revert "firmware: dmi_scan: Use lowercase letters for UUID"

From: Peter Korsgaard
Date: Wed Dec 05 2018 - 16:13:59 EST


This reverts commit 712ff25450bd01366301eef81c33e865d901e7b7.

The output of dmi_save_uuid() is exposed to user space as
/sys/devices/virtual/dmi/id/*_uuid, so this breaks backwards compatibility,
E.G. I have systems that include the content of dmi/id/product_uuid as part
of the keyphrase for cryptsetup luksOpen.

As the change was purely cosmetical, revert it to fix such breakage.
