Subject: firmware: Add missing attributes to EFI variable attribute print out
from sysfs
From: Khalid Aziz <[email protected]>
commit 7083909023bbe29b3176e92d2d089def1aa7aa1e upstream.
Some of the EFI variable attributes are missing from print out from
/sys/firmware/efi/vars/*/attributes. This patch adds those in. It also
updates code to use pre-defined constants for masking current value
of attributes.
