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

From: Markus Elfring <elfring@...rs.sourceforge.net>

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.
