Hi Bart, kernel test robot noticed the following build warnings: [auto build test WARNING on mkp-scsi/for-next] [cannot apply to jejb-scsi/for-next linus/master v6.11-rc7 next-20240913] [If your patch is applied to the wrong git tree, kindly drop us a note.

Prepare for moving a ufshcd_device_init() call from inside ufshcd_probe_hba() into the ufshcd_probe_hba() callers by introducing the function ufshcd_process_device_init_result(). No functionality has been changed.
