From: Hans de Goede Date: Tue, 16 Sep 2014 16:36:52 +0000 (+0200) Subject: uas: Add no-report-opcodes quirk X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=734016b00b50a3c6a0e1fc1b7b217e783f5123a1;p=linux-beck.git uas: Add no-report-opcodes quirk 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 Cc: stable@vger.kernel.org Reported-and-tested-by: Claudio Bizzarri Signed-off-by: Hans de Goede Signed-off-by: Greg Kroah-Hartman --- diff --git a/Documentation/kernel-parameters.txt b/Documentation/kernel-parameters.txt index dd4fe9880e4a..1edd5fdc629d 100644 --- a/Documentation/kernel-parameters.txt +++ b/Documentation/kernel-parameters.txt @@ -3522,6 +3522,8 @@ bytes respectively.
