            Bug ID: 210686
           Summary: NCQ_TRIM_BROKEN quirk mismatch
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern

patch for ata_da.c

Crucial MX200 is not blacklisted, but NCQ_TRIM_BROKEN quirk is enabled.

> ada0 at ahcich0 bus 0 scbus0 target 0 lun 0
> ada0: <Crucial CT250MX200SSD3 MU03> ACS-3 ATA SATA 3.x device

> ada0: quirks=0x2<NCQ_TRIM_BROKEN>

Mismatched quirk entry is:

> 		/*
> 		 * Crucial M500 SSDs all other firmware
> 		 * NCQ Trim doesn't work
> 		 */
> 		{ T_DIRECT, SIP_MEDIA_FIXED, "*", "Crucial CT*M500*", "*" },
> 		/*quirks*/ADA_Q_NCQ_TRIM_BROKEN

"Crucial CT*M500*" is equivalent to "Crucial CT*".
(wildcard '*' in pattern matches rest of name (in cam.c))

I wrote a patch. This patch also includes fix for Micron M510/M550.
