Subject: [PATCH] firmware: dmi: Add access to the SKU ID string
|
||
|
|
|
||
|
|
This is used in some systems from user space for determining the identity
|
||
|
|
of the device.
|
||
|
|
|
||
|
|
Expose this as a file so that that user-space tools don't need to read
|
||
|
|
from /sys/firmware/dmi/tables/DMI
|
