[PATCH] staging: rtl8723bs: Replace the comparision method

From: izabela . bakollari
Date: Mon Oct 26 2020 - 18:09:35 EST

From: Izabela Bakollari <izabela.bakollari@xxxxxxxxx>

Replace the value comparision method by using the logical NOT
operator instead of comparing the value to NULL.

Signed-off-by: Izabela Bakollari <izabela.bakollari@xxxxxxxxx>
