    usb: usb-storage: No additional quirks need to be added to the EL-R12 optical drive.
    
    [ Upstream commit 955a48a5353f4fe009704a9a4272a3adf627cd35 ]
    
    The optical drive of EL-R12 has the same vid and pid as INIC-3069,
    as follows:
    T:  Bus=02 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#=  3 Spd=5000 MxCh= 0
    D:  Ver= 3.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 9 #Cfgs=  1
    P:  Vendor=13fd ProdID=3940 Rev= 3.10
    S:  Manufacturer=HL-DT-ST
    S:  Product= DVD+-RW GT80N
    S:  SerialNumber=423349524E4E38303338323439202020
    C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=144mA
    I:* If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=02 Prot=50 Driver=usb-storage
    E:  Ad=83(I) Atr=02(Bulk) MxPS=1024 Ivl=0ms
    E:  Ad=0a(O) Atr=02(Bulk) MxPS=1024 Ivl=0ms
    
    This will result in the optical drive device also adding
    the quirks of US_FL_NO_ATA_1X. When performing an erase operation,
    it will fail, and the reason for the failure is as follows:
    [  388.967742] sr 5:0:0:0: [sr0] tag#0 Send: scmd 0x00000000d20c33a7

    [  388.967803] sr 5:0:0:0: Notifying upper driver of completion (result 8100002)
    [  388.967834] sr 5:0:0:0: [sr0] tag#0 0 sectors total, 0 bytes done.
    
    For the EL-R12 standard optical drive, all operational commands
    and usage scenarios were tested without adding the IGNORE_RESIDUE quirks,
    and no issues were encountered. It can be reasonably concluded
    that removing the IGNORE_RESIDUE quirks has no impact.

This commit will be modified by commit 0831269b5f71 ("usb: usb-storage:
Maintain minimal modifications to the bcdDevice range.") in Greg's usb-linus branch, which has not yet been merged into the mainline kernel. The two commits should be added to the -stable kernels at the same time, if possible, which probably means holding off on this one until the next round.
