Subject: [PATCH] staging: rtl8723bs: remove redundant assignment to variable ret

From: Colin Ian King <colin.king@...onical.com>

The variable ret is being assigned an error return value that is never
read, the control passes to a return statement and ret is never referenced.
Remove the redundant assignment. Also remove an empty line.

Addresses-Coverity: ("Unused value")
