Subject: fix medium presence misdetection in usb storage device
|
|
References: bnc#362850

From reading the SCSI spec it seems that having the valid bit 0 (0x70
|
|
checked in scsi_sense_valid) should does not invalidate the ASC or ASQ.
|
|
[See page 37 of spc4r02.pdf]. It should only invalidate the INFORMATION
|
|
field. Therefore remove the sense_valid check from the USB quirk.
