From: Hans de Goede Date: Mon, 19 Mar 2018 15:34:00 +0000 (+0100) Subject: libata: Modify quirks for MX100 to limit NCQ_TRIM quirk to MU01 version X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=d418ff56b8f2d2b296daafa8da151fe27689b757;p=openwrt%2Fstaging%2Fblogic.git libata: Modify quirks for MX100 to limit NCQ_TRIM quirk to MU01 version When commit 9c7be59fc519af ("libata: Apply NOLPM quirk to Crucial MX100 512GB SSDs") was added it inherited the ATA_HORKAGE_NO_NCQ_TRIM quirk from the existing "Crucial_CT*MX100*" entry, but that entry sets model_rev to "MU01", where as the entry adding the NOLPM quirk sets it to NULL. This means that after this commit we no apply the NO_NCQ_TRIM quirk to all "Crucial_CT512MX100*" SSDs even if they have the fixed "MU02" firmware. This commit splits the "Crucial_CT512MX100*" quirk into 2 quirks, one for the "MU01" firmware and one for all other firmware versions, so that we once again only apply the NO_NCQ_TRIM quirk to the "MU01" firmware version.
