Subject: [PATCH] uas: Add US_FL_NO_ATA_1X for linux tcm_usb_gadget
The linux kernel's tcm_usb_gadget requires the US_FL_NO_ATA_1X quirk.
It does not respond to the ATA_12 family of commands and hangs. The host
prevents the issuing of ATA_12 commands to the TCM module, by introducing
this quirk, the host is permitted to proceed with other operations.
