commit dd957493baa586f1431490f97f9c7c45eaf8ab10 upstream.
We've received a bugreport that using LPM with a SAMSUNG MZ7TE512HMHP-000L1 SSD leads to system instability, we already have a quirk for the MZ7TD256HAFV-000L9, which is also a Samsun EVO 840 / PM851 OEM model, so it seems some of these models have a LPM issue.
This commits adds a NOLPM quirk for the model string from the new bugeport, to avoid the reported stability issues.
