- as the callback can schedule work, URBs must be killed first - if the driver causes an autoresume, the caller must handle locking Signed-off-by:

The guarding flag must be set and tested under spinlock and cleared before the URBs are resubmitted in resume. Signed-off-by:

There's a window under which cdc-wdm may submit an URB to a device about to be suspended. This introduces a flag to prevent it. Signed-off-by:

The recent commit "usb: musb: Add context save and restore support" added some stubs for the Blackfin code so things would compile, but it also added a bunch of warnings due to missing return statements. Signed-off-by:

The USB PHY on current Blackfin processors is a UTMI+ level 2 PHY. However, it has no ULPI support - so there are no registers at all. That means accesses to ULPI_BUSCONTROL have to be abstracted away like other MUSB registers. This fixes building for Blackfin parts again. Signed-off-by:

CONFIG_ARCH_OMAP34XX is now CONFIG_ARCH_OMAP3. But since drivers/usb/musb/omap2430.c use CONFIG_PM for these registers and functions, do the same for the header. Otherwise we get the following for most omap3 defconfigs: drivers/usb/musb/omap2430.c:261: error: expected identifier or '(' before 'do' drivers/usb/musb/omap2430.c:261: error: expected identifier or '(' before 'while' drivers/usb/musb/omap2430.c:268: error: expected identifier or '(' before 'do' drivers/usb/musb/omap2430.c:268: error: expected identifier or '(' before 'while' Signed-off-by:Tony Lindgren <tony@atomide.com> Signed-off-by:

The recent commit "usb: musb: Fix for isochronous IN transfer" (f82a689f) seems to have been against an older kernel version. It uses the old style naming of variables. Unfortunately, this breaks building for most MUSB users out there since "bDesiredMode" has been renamed to "desired_mode". Signed-off-by:

Clemens Ladisch authored
The EHCI driver stores in usb_host_endpoint.hcpriv a pointer to either an ehci_qh or an ehci_iso_stream structure, and uses the contents of the hw_info1 field to distinguish the two cases. After ehci_qh was split into hw and sw parts, ehci_iso_stream must also be adjusted so that it again looks like an ehci_qh structure. This fixes a NULL pointer access in ehci_endpoint_disable() when it tries to access qh->hw->hw_info1. Signed-off-by:

When isochronous URBs are shorter than one frame and when more than one ITD in a frame has been completed before the interrupt can be handled, scan_periodic() completes the URBs in the order in which they are found in the descriptor list. Therefore, the descriptor list must contain the ITDs in the correct order, i.e., a new ITD must be linked in after any previous ITDs of the same endpoint. This should fix garbled capture data in the USB audio drivers. Signed-off-by:

I found a DLink DWM 652 U5 USB 3G modem has product ID 0xce1e instead of orignal 0xce16. The new ID is added. And I found there are two entries for 0xce16, one has raw number, the other has symbol DLINK_PRODUCT_DWM_652_U5. This is fixed too. Signed-off-by:

SL11R-IDE 2.6c (at least) reports wrong capacity (one sector more). Reading that last sector causes the device not to work anymore (and looks like HAL or something does that automatically after plugging in): sd 5:0:0:0: [sdc] Device not ready sd 5:0:0:0: [sdc] Result: hostbyte=0x00 driverbyte=0x08 sd 5:0:0:0: [sdc] Sense Key : 0x2 [current] sd 5:0:0:0: [sdc] ASC=0x0 ASCQ=0x0 sd 5:0:0:0: [sdc] CDB: cdb[0]=0x28: 28 00 04 a8 b5 70 00 00 01 00 Add unusual_devs entry to fix the capacity.

It is possible to have a multi-port device with a port lacking an in or out bulk endpoint. Only checking for num_bulk_in or num_bulk_out is thus not sufficient to determine whether a specific port has an in or out bulk endpoint. This fixes potential null pointer dereferences in the generic open and write routines, as well as access to uninitialised fifo in write_room and chars_in_buffer. Also let write fail with ENODEV (instead of 0) on missing out endpoint (also on zero-length writes). Signed-off-by:

This patch (as1352) fixes a bug in the way isochronous input data is returned to userspace for usbfs transfers. The entire buffer must be copied, not just the first actual_length bytes, because the individual packets will be discontiguous if any of them are short. Reported-by:

Detect if a processor is physically present before evaluating _PDC. We want this because some BIOS will provide a _PDC even for processors that are not present. These bogus _PDC methods then attempt to load non-existent tables, which causes problems. Avoid those bogus landmines. Acked-by:
