processing of asymmetric connected lanes

[PATCH v3 0/2] processing of asymmetric connected lanes

Posted by SEO HOYOUNG 1 month, 2 weeks ago

Performance problems may occur if there is a problem with the
asymmetric connected lane such as h/w failure.
Currently, only check connected lane for rx/tx is checked if it is not 0.
But it should also be checked if it is asymmetrically connected.
So if it is an asymmetric connected lane, an error occurs.

v1 -> v2: add error routine.
ufs initialization error occurs in case of asymmetic connected

v2 -> v3: split two patches

SEO HOYOUNG (2):
  scsi: ufs: core: check asymmetric connected lanes
  scsi: ufs: core: reflect function execution result in return

Applied to 6.13/scsi-queue, thanks!
