The code does not implement the comment, so timestamps for long traces become confusing instead of wrapping neatly as expected. This was actually observed. Fortunately for API being in debugfs, we can just fix this instead of staying bug-for-bug compatible. Double fortunately, the stable binary API is not affected.

This patch (as1344) removes references to port->port.count from the USB serial drivers. Now that serial ports are properly reference counted, port.count checking is unnecessary and incorrect. Drivers should assume that the port is in use from the time the open method runs until the close method is called.

We have lots of callers that do not need to do this in the first place. Remove the calls as they both cost CPU and for big buffers can mess up the multi-page allocation avoidance. Signed-off-by: NAlan Cox <alan@linux.intel.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

While looping over the interfaces, if usb_hcd_alloc_bandwidth() fails it calls hcd->driver->reset_bandwidth(), so there was no need to reinstate the interface again. If no break occurred, the index equals config->desc.bNumInterfaces. A subsequent usb_control_msg() failure resulted in a read from config->interface[config->desc.bNumInterfaces] at label reset_old_alts. In either case the last interface should be skipped.

This patch (as1347) makes some adjustments to the way usb-storage handles the request-queue parameters. USB host controllers are able to handle arbitrarily long scatter-gather lists, since they are limited only by main memory and not by the controller hardware. Hence the sg_tablesize field in the host template can be increased to the maximum value. Drivers like usb-storage aren't supposed to touch the queue's max_sectors parameter; instead they are supposed to use the max_hw_sectors value. Accordingly, the patch replaces calls of queue_max_sectors() with calls of queue_max_hw_sectors(). Oddly enough, the blk_queue_max_sectors() routine is nevertheless still appropriate. The existing code imposes a limit of SCSI_DEFAULT_MAX_SECTORS (1024) on the values accepted by the max_sectors attribute file. There's no reason not to accept larger values, so the limit is removed. (It would be nice to change the file's name to max_hw_sectors, but the old name is already a well-established API.)

Texas Instruments DA8xx/OMAP-L1x OHCI glue layer. This OHCI implementation is not without quirks: there's only one physical port despite the root hub reporting two; the port's power control and over-current status bits are not connected to any pins, however, at least on the DA830 EVM board, those signals are connected via GPIO, thus the provision was made for overriding the OHCI port power and over-current bits at the board level...

A crash has been reported with sierra driver on disconnect with Ubuntu/Lucid distribution based on kernel-2.6.32. The cause of the crash was determined as "NULL tty pointer was being referenced" and the NULL pointer was passed by sierra_indat_callback(). This patch modifies sierra_indat_callback() function to check for NULL tty structure pointer. This modification prevents a crash from happening when the device is disconnected.

由 Jason Wessel 提交于
This patch addresses two problems: 1) Bulk reads should always use the DATA0 for the pid, and the write PID should toggle between DATA0 and DATA1. The fix is using dbgp_pid_write_update() and dbgp_pid_read_update(). 2) The delay loop for waiting for a transaction was not long enough to always complete the initial handshake inside dbgp_wait_until_done(). After the initial handshake the maximum delay length is never reached. The combined result of these two changes allows for the removal of the forced resynchronization where a bulk write was issued with a dummy data payload only to get the device to start accepting data writes again.

A bunch of USB gadget drivers where never ported from the linux 2.4 series to 2.6 kernels. However there's some code still in the tree for them which isn't used and is probably untested for ages.

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.
