If anyone has any objections, please let me know. ------------------ From: Hans de Goede commit 734016b00b50a3c6a0e1fc1b7b217e783f5123a1 upstream. Besides the ASM1051 (*) needing sdev->no_report_opcodes = 1, it turns out that the JMicron JMS567 also needs it to work properly with uas (usb-storage always sets it). Since some of the scsi devs were not to keen on the idea to outrightly set sdev->no_report_opcodes = 1 for all uas devices, so add a quirk for this, and set it for the JMS567. *) Which has become a non-issue since we've completely blacklisted uas on the ASM1051 for other reasons Reported-and-tested-by: Claudio Bizzarri Signed-off-by: Hans de Goede Signed-off-by: Greg Kroah-Hartman --- Documentation/kernel-parameters.txt | 2 ++ drivers/usb/storage/uas.c | 4 ++++ drivers/usb/storage/unusual_uas.h | 7 +++++++ drivers/usb/storage/usb.c | 5 ++++- include/linux/usb_usual.h | 2 ++ 5 files changed, 19 insertions(+), 1 deletion(-) --- a/Documentation/kernel-parameters.txt +++ b/Documentation/kernel-parameters.txt @@ -3522,6 +3522,8 @@ bytes respectively.
