[PATCH 4/6] firmware-qemu_fw_cfg: Improve a size determination in fw_cfg_build_symlink()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sun, 18 Sep 2016 14:02:02 +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.
