    Subject[PATCH 08/18] [media] RedRat3: Improve another size determination in redrat3_send_cmd()
    From
    Date
    From: Markus Elfring <elfring@users.sourceforge.net>
    Date: Thu, 13 Oct 2016 13:31:17 +0200

    Replace the specification of a data type by a pointer dereference
    as the parameter for the operator "sizeof" to make the corresponding size
    determination a bit safer.
