[PATCH 5.9 360/757] staging: rtl8712: Fix enqueue_reorder_recvframe()

From: Greg Kroah-Hartman
Date: Tue Oct 27 2020 - 11:44:22 EST


From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ Upstream commit 29838144f280fc03ca06a621568f34e1d0a65a4f ]

The logic of this function was accidentally broken by a checkpatch
inspired cleanup. I've modified the code to restore the original
behavior and also make checkpatch happy.

Fixes: 98fe05e21a6e ("staging: rtl8712: Remove unnecesary else after return statement.")
