usb-storage/SCSI: blacklist FUA on JMicron 152d:2566 USB-SATA controller

uas: Add no-report-opcodes quirk for Simpletech devices with id 4971:8017

storage: Revise/fix quirk for 04E6:000F SCM USB-SCSI converter

2015-01-25T13:20:42Z

I recently posted a patch ("storage: Add quirk for another SCM-based USB-SCSI converter") to add a quirk for the converter with ID 04E6:000F, which is listed along with 04E6:000B in the Windows INF file for the Startech ICUSBSCSI2 as "eUSB SCSI Adapter (Bus Powered)". The already-present quirk for 04E6:000B has USB_SC_SCSI/USB_PR_BULK, not USB_SC_DEVICE/USB_PR_DEVICE. Change the 04E6:000F quirk to match that, since it will probably be required.

usb: phy: never defer probe in non-OF case

2015-01-19T18:50:27Z

In practice failure to find phy when requested in non-OF case means it will never become available, so __usb_find_phy() must return -ENODEV and not -EPROBE_DEFER. This fixes a regression caused by commit 9c9d82492b73 (usb: phy: Fix deferred probing), where the USB controller driver is left infinitely into deferred probe when there are no phys.

usb: dwc2: call dwc2_is_controller_alive() under spinlock

2015-01-19T15:41:49Z

This patch fixes the following problem: data transmission in direction IN break unless the GSNPSID register access is done with spinlock held. This issue occurs at least in Exynos4412 SoC, probably in many SoC's from Exynos familly. The problem is described here: https://lkml.org/lkml/2014/12/22/185 And there is linux mailing list discussion: https://lkml.org/lkml/2015/1/14/17 Signed-off-by: Robert Baldyga Signed-off-by: Felipe Balbi

usb: dwc3: gadget: Stop TRB preparation after limit is reached

2015-01-14T17:29:05Z

DWC3 gadget sets up a pool of 32 TRBs for each EP during initialization. This means, the max TRBs that can be submitted for an EP is fixed to 32. Since the request queue for an EP is a linked list, any number of requests can be queued to it by the gadget layer. However, the dwc3 driver must not submit TRBs more than the pool it has created for. This limit wasn't respected when SG was used resulting in submitting more than the max TRBs, eventually leading to non-transfer of the TRBs submitted over the max limit. Root cause: When SG is used, there are two loops iterating to prepare TRBs: - Outer loop over the request_list - Inner loop over the SG list The code was missing break to get out of the outer loop.
