2010-02-26block: Rename blk_queue_max_sectors to blk_queue_max_hw_sectorsMartin K. Petersen
The block layer calling convention is blk_queue_<limit name>. blk_queue_max_sectors predates this practice, leading to some confusion. Rename the function to appropriately reflect that its intended use is to set max_hw_sectors. Also introduce a temporary wrapper for backwards compability. This can be removed after the merge window is closed. Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

With CONFIG_USB_ULPI=y, CONFIG_USB<=m, CONFIG_PCI=n and CONFIG_USB_OTG_UTILS=n, which is the default used for mx31moboard, the build for all mx3 platforms fails because drivers/usb/otg/ulpi.c where otg_ulpi_create is defined is not compiled.

2010-02-16USB: usbfs: properly clean up the as structure on error pathsLinus Torvalds
I notice that the processcompl_compat() function seems to be leaking the 'struct async *as' in the error paths. I think that the calling convention is fundamentally buggered. The caller is the one that did the "reap_as()" to get the as thing, the caller should be the one to free it too. Freeing it in the caller also means that it very clearly always gets freed, and avoids the need for any "free in the error case too".

2010-02-05usb: r8a66597-hcd: Fix up spinlock recursion in root hub polling.Paul Mundt
The current root hub polling code exhibits a spinlock recursion on the private controller lock. r8a66597_root_hub_control() is called from r8a66597_timer() which grabs the lock and disables IRQs. The following chain emerges: r8a66597_timer() <-- lock taken r8a66597_root_hub_control() r8a66597_check_syssts() usb_hcd_poll_rh_status() <-- acquires the same lock /* insert death here */ The entire chain requires IRQs to be disabled, so we just unlock and relock around the call to usb_hcd_poll_rh_status() while leaving the IRQ state unchanged.

2010-02-05usb: r8a66597-hcd: Flush the D-cache for the pipe-in transfer buffers.Paul Mundt
This implements the same D-cache flushing logic for r8a66597-hcd as Catalin's isp1760 (http://patchwork.kernel.org/patch/76391/) change, with the same note applying here as well: When the HDC driver writes the data to the transfer buffers it pollutes the D-cache (unlike DMA drivers where the device writes the data). If the corresponding pages get mapped into user space, there are no additional cache flushing operations performed and this causes random user space faults on architectures with separate I and D caches (Harvard) or those with aliasing D-cache.

2010-01-20USB: fix usbstorage for 2770:915d delivers no FATRyan May
Resolves kernel.org bug 14914. Remove entry for 2770:915d (usb digital camera with mass storage support) from unusual_devs.h. The fix triggered by the entry causes the file system on the camera to be completely inaccessible (no partition table, the device is not mountable). The patch works, but let me clarify a few things about it. All the patch does is remove the entry for this device from the drivers/usb/storage/unusual_devs.h, which is supposed to help with a problem with the device's reported size (I think). I'm pretty sure it was originally added for a reason, so I'm not sure removing it won't cause other problems to reappear. Also, I should note that this unusual_devs.h entry was present (and activating workarounds) in 2.6.29, but in that version everything works fine. Starting with 2.6.30, things no longer work.

After the device reset and re-configuration, the device and the xHCI host think they are using alternate setting 0 of all interfaces. However, the USB core keeps track of the old state, which may include non-zero alternate settings. It uses intf->cur_altsetting to keep the endpoint sysfs files for the old state across the reset. The bandwidth allocation functions need to know what the xHCI host thinks the current alternate settings are, so original patch set intf->cur_altsetting to the alternate setting 0. This caused duplicate endpoint files to be created. The solution is to not set intf->cur_altsetting before calling usb_set_interface() in usb_reset_and_verify_device(). Instead, we add a new flag to struct usb_interface to tell usb_hcd_alloc_bandwidth() to use alternate setting 0 as the currently installed alternate setting.

2010-01-20USB: add missing delay during remote wakeupAlan Stern
This patch (as1330) fixes a bug in khbud's handling of remote wakeups. When a device sends a remote-wakeup request, the parent hub (or the host controller driver, for directly attached devices) begins the resume sequence and notifies khubd when the sequence finishes. At this point the port's SUSPEND feature is automatically turned off. However the device needs an additional 10-ms resume-recovery time (TRSMRCY in the USB spec). Khubd does not wait for this delay if the SUSPEND feature is off, and as a result some devices fail to behave properly following a remote wakeup. This patch adds the missing delay to the remote-wakeup path. It also extends the resume-signalling delay used by ehci-hcd and uhci-hcd from 20 ms (the value in the spec) to 25 ms (the value we use for non-remote-wakeup resumes). The extra time appears to help some devices.

When remote wakeup is enabled, this is undesirable behavior. The patch checks first to see if any port resumes are in progress, and if they are then it fails the root-hub suspend with -EBUSY.

2010-01-20USB: EHCI: fix handling of unusual interrupt intervalsAlan Stern
This patch (as1320) fixes two problems related to interrupt-URB scheduling in ehci-hcd. URBs with an interval of 2 or 4 microframes aren't handled. For the time being, the patch reduces to interval to 1 uframe. URBs are constrained to have an interval no larger than 1024 frames by usb_submit_urb(). But some EHCI controllers allow use of a schedule as short as 256 frames; for these controllers we may have to decrease the interval to the actual schedule length. The second problem isn't very significant since few devices expose interrupt endpoints with an interval larger than 256 frames. But the first problem is critical; it will prevent the kernel from working with devices having interrupt intervals of 2 or 4 uframes.

Some of these workarounds are already in place, but labeled as affecting all BF52x parts. Since we have official anomaly numbers now, use those defines. And since writing to the FIFO has a similar hang issue as reading from the FIFO, implement the workaround there too when necessary.

2009-12-23USB: musb: Fix array index out of bounds issueMaulik Mankad
This patch fixes the below array index out of bounds issue. Buffer overflow, array index of 'aInfo' may be out of bounds. Array 'aInfo' of size 78 may use index value(s) 6..84 The data stored in 'aInfo' array exceeds the array size of 78. This patch increases the size of this array to hold the string correctly without any memory corruption. This issue was reported by Klockwork tool.

2009-12-23USB: musb: fix for crash in DM646x USB when (CPPI)DMA is enabledSwaminathan S
Race condition exists between the cppi_interrupt handler and davinci_interrupt handler w.r.t completing a TX IO. Since DM646x has seperate DMA and USB endpoint interrupts cppi_interrupt handler needs to hold the lock while operating on the endpoint. Update over previous patch to avoid taking the lock if already taken. Tested on DM644x, DM355 and DM646x platforms.

This is a (almost) sort-only patch to sort FTDI device product ID definitions in new ftdi_sio_ids.h header. Advantage is that new device ID submissions will now have a specific (sorted) position - less future merge conflicts. Compile-tested, based on _current_ mainline git. Minor checkpatch.pl warnings were eliminated whereever it made sense, very minor text changes. Signed-off-by: Andreas Mohr <andi@lisas.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
