[PATCH v3 2/5] staging: rtl8712: style fix multiple line dereferences

From: Martin Homuth
Date: Tue Dec 19 2017 - 11:33:15 EST

This patch fixes various coding style issues in the rtl8712 module as
noted by checkpatch.pl related to dereferencing over multiple lines.

It fixes the following checkpatch.pl warning:

WARNING: Avoid multiple line dereference - prefer %s
