Subject: [PATCH 2/5] radeon_backlight: Improve a size determination in
 radeonfb_bl_init()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 27 Nov 2017 21:30:06 +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.

This issue was detected by using the Coccinelle software.
