[v6,08/11] scsi: ufs: core: Expand the ufshcd_device_init(hba, true) call

Commit Message

Bart Van Assche Oct. 16, 2024, 8:12 p.m. UTC

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.
