Subject: [PATCH v6 08/11] scsi: ufs: core: Expand the ufshcd_device_init(hba, true) call
Date: Wed, 16 Oct 2024 13:12:04 -0700	[thread overview]
Message-ID: <20241016201249.2256266-9-bvanassche@acm.org> (raw)
In-Reply-To: <20241016201249.2256266-1-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.
