Subject: [PATCH AUTOSEL 5.4 023/205] rtw88: fix error handling when setup efuse info
Date: Thu, 16 Jan 2020 11:39:58 -0500 [thread overview]
Message-ID: <20200116164300.6705-23-sashal@kernel.org> (raw)
In-Reply-To: <20200116164300.6705-1-sashal@kernel.org>
From: Ping-Ke Shih <pkshih@realtek.com>
[ Upstream commit f4268729eb1eefe23f6746849c1b5626d9030532 ]
Disable efuse if the efuse is enabled when we failed to setup the efuse
information, otherwise the hardware will not turn off.
