libata: Apply NOLPM quirk for SanDisk SD7UB3Q*G1001 SSDs
Richard Jones has reported that using med_power_with_dipm on a T450s with a Sandisk SD7UB3Q256G1001 SSD (firmware version X2180501) is causing the machine to hang. Switching the LPM to max_performance fixes this, so it seems that this Sandisk SSD does not handle LPM well. Note in the past there have been bug-reports about the following Sandisk models not working with min_power, so we may need to extend the quirk list in the future: name - firmware Sandisk SD6SB2M512G1022I - X210400 Sandisk SD6PP4M-256G-1006 - A200906 Cc: stable@vger.kernel.org Cc: Richard W.M.
