Subject: [PATCH 1/1] efi: Correct Macmini capitalisation in uefi cert quirk
|
||
|
|
|
||
|
|
It turns out Apple doesn't capitalise the "mini" in "Macmini", which is
|
||
|
|
inconsistent with other model line names.
|
||
|
|
|
||
|
|
Correct the capitalisation of Macmini in the quirk for skipping loading
|
||
|
|
platform certs on T2 Macs.
