Subject: [PATCH 08/11] rtw88: power on again if it was already on
Date: Wed, 12 Jun 2019 14:45:14 +0800 [thread overview]
Message-ID: <1560321917-17751-9-git-send-email-yhchuang@realtek.com> (raw)
In-Reply-To: <1560321917-17751-1-git-send-email-yhchuang@realtek.com>
From: Yan-Hsuan Chuang <yhchuang@realtek.com>
We could fail to power on because it was already on. If the return
value is -EALREADY, power off and then power on again to turn on the
hardware as expected.
