Subject: [PATCH] wifi: rtl8xxxu: Simplify the error handling code
Date: Thu, 18 Aug 2022 15:33:52 +0800 [thread overview]
Message-ID: <20220818073352.3156288-1-zheyuma97@gmail.com> (raw)
Since the logic of the driver's error handling code has changed, the
previous dead store and checks are not needed.
