Subject: [PATCH 02/18] [media] RedRat3: Move two assignments in
 redrat3_transmit_ir()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 13 Oct 2016 10:25:57 +0200

Move the assignment for the data structure member "transmitting"
and the local variable "curlencheck" behind the source code
for memory allocations by this function.
