Subject: USB: ene_usb6250: fix SCSI residue overwriting

From: Alan Stern <[email protected]>

[ Upstream commit aa18c4b6e0e39bfb00af48734ec24bc189ac9909 ]

In the ene_usb6250 sub-driver for usb-storage, the SCSI residue is not reported correctly. The residue is initialized to 0, but this value is overwritten whenever the driver sends firmware to the card reader before performing the current command. As a result, a valid READ or WRITE operation appears to have failed, causing the SCSI core to retry the command multiple times and eventually fail.

This patch fixes the problem by resetting the SCSI residue to 0 after sending firmware to the device.
