Subject: [PATCH v4 07/10] scsi: ufs: core: Expand the ufshcd_device_init(hba, true) call
Date: Thu, 5 Sep 2024 15:01:33 -0700 [thread overview]
Message-ID: <20240905220214.738506-8-bvanassche@acm.org> (raw)
In-Reply-To: <20240905220214.738506-1-bvanassche@acm.org>
Expand the ufshcd_device_init(hba, true) call and remove all code that
depends on init_dev_params == false. This change prepares for combining
the two scsi_add_host() calls.
