[Regression] libata: sata_down_spd_limit should return if driver has not recorded sstatus speed

[Joseph Salisbury]

Hi David,

A kernel bug report was opened against Ubuntu [0]. This bug is a
regression introduced in v4.15-rc4. The following commit was identified
as the cause of the regression:

ÂÂÂÂÂÂÂ 2dc0b46b5ea3 ("libata: sata_down_spd_limit should return if
driver has not recorded sstatus speed")

I was hoping to get your feedback, since you are the patch author. Do
you think gathering any additional data will help diagnose this issue,
or would it be best to submit a revert request?


Thanks,

Joe
