Browse source

[ Upstream commit d34ee53570 ]

In function hisi_sas_controller_prereset(), -ENOSYS (Function not
implemented) should be returned if the driver does not support .soft_reset.
Returns -EPERM (Operation not permitted) if HISI_SAS_RESETTING_BIT is
already be set.

In function _suspend_v3_hw(), returns -EPERM (Operation not permitted) if
HISI_SAS_RESETTING_BIT is already be set.
