   4 Subject: libata: Extend quirks for the ST1000LM024 drives with NOLPM quirk

   8 commit 31f6264e225fb92cf6f4b63031424f20797c297d upstream.
   9
  10 We've received a bugreport that using LPM with ST1000LM024 drives leads
  11 to system lockups. So it seems that these models are buggy in more then
  12 1 way. Add NOLPM quirk to the existing quirks entry for BROKEN_FPDMA_AA.
