Subject: [PATCH v4 3/3] rtw88: 8822c: fix lc calibration timing
Date: Mon, 26 Apr 2021 09:32:52 +0800 [thread overview]
Message-ID: <20210426013252.5665-3-pkshih@realtek.com> (raw)
In-Reply-To: <20210426013252.5665-1-pkshih@realtek.com>
From: Po-Hao Huang <phhuang@realtek.com>
Before this patch, we use value from 2 seconds ago to decide
whether we should do lc calibration.
Although this don't happen frequently, fix flow to the way it should be.
Fixes: 7ae7784ec2a8 ("rtw88: 8822c: add LC calibration for RTL8822C")
