Subject: [PATCH 2/3] dmaengine: timb_dma: Improve a size determination in
 td_alloc_init_desc()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 25 Dec 2023 10:50:10 +0100

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.
