Subject: [PATCH v4 4/8] scsi: ufs: Move ufshcd_get_max_pwr_mode() to ufshcd_device_params_init()
Date: Mon, 20 Jan 2020 14:08:16 +0100 [thread overview]
Message-ID: <20200120130820.1737-5-huobean@gmail.com> (raw)
In-Reply-To: <20200120130820.1737-1-huobean@gmail.com>
From: Bean Huo <beanhuo@micron.com>
ufshcd_get_max_pwr_mode() only need to be called once while booting, take
it out from ufshcd_probe_hba() and inline into ufshcd_device_params_init().
