Subject: [PATCH 2/2] [media] airspy: Improve a size determination in

From: Markus Elfring <>
Date: Sun, 17 Sep 2017 11:03:21 +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.
