[PATCH 3/3] coresight: etb10: Improve a size determination in etb_alloc_buffer()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Fri, 12 May 2017 20:36:03 +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.
