Subject[PATCH 2/2] [media] dvb_usb_core: Improve a size determination in two functions
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 18 Sep 2017 09:36:33 +0200

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