[PATCH v1] efi/apple-properties: Device core takes care of empty properties

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is no need to artificially supply a property length and fake data
if property has type of boolean.

Remove redundant piece of data and code.
