[PATCH 09/30] ACPI-processor: Improve a size determination in acpi_processor_get_psd()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 6 Sep 2016 18:48:37 +0200

Replace the specification of a data structure by pointer dereferences
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
