Subject: [media] as102_fe: Improve a size determination in as102_attach()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 29 Aug 2017 21:30:38 +0200

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

This issue was detected by using the Coccinelle software.
