Subject: [PATCH 063/108] scsi: hisi_sas: Recover PHY state according to the
|
|
status before reset
|
|
|
|
mainline inclusion
|
|
from mainline-v5.10-rc1
|

commit 69f4ec1edb136d2d2511d1ef96f94ef0aeecefdf
|
|
category: feature
|
|
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8F81U
|
|
|

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=69f4ec1edb136d2d2511d1ef96f94ef0aeecefdf

----------------------------------------------------------------------
|
|
|
|
Currently the PHY state is set according to the state of the PHYs after
|
|
reset. This is invalid as the PHYs are already re-initialized.
|
|
|
|
Set PHY state according to the state before the reset instead of after.
