This patch (as1207) converts usb-storage's sddr09 subdriver into a separate module. An unexpected complication arises because of DPCM devices, in which one LUN uses the sddr09 transport and one uses the standard CB transport. Since these devices can be used even when USB_STORAGE_SDDR09 isn't configured, their entries in unusual_devs.h require special treatment. If SDDR09 isn't configured then the entries remain in unusual_devs.h; if it is then the entries are present in unusual_sddr09.h instead. Signed-off-by:

This patch (as1206) is the first step in converting usb-storage's subdrivers into separate modules. It makes the following large-scale changes: Remove a bunch of unnecessary #ifdef's from usb_usual.h. Not truly necessary, but it does clean things up. Move the USB device-ID table (which is duplicated between libusual and usb-storage) into its own source file, usual-tables.c, and arrange for this to be linked with either libusual or usb-storage according to whether USB_LIBUSUAL is configured. Add to usual-tables.c a new usb_usual_ignore_device() function to detect whether a particular device needs to be managed by a subdriver and not by the standard handlers in usb-storage. Export a whole bunch of functions in usb-storage, renaming some of them because their names don't already begin with "usb_stor_". These functions will be needed by the new subdriver modules. Split usb-storage's probe routine into two functions. The subdrivers will call the probe1 routine, then fill in their transport and protocol settings, and then call the probe2 routine. Take the default cases and error checking out of get_transport() and get_protocol(), which run during probe1, and instead put a check for invalid transport or protocol values into the probe2 function. Add a new probe routine to be used for standard devices, i.e., those that don't need a subdriver. This new routine checks whether the device should be ignored (because it should be handled by ub or by a subdriver), and if not, calls the probe1 and probe2 functions. Signed-off-by:

With "nousb" cmdline booting, built-in serial drivers (ie. airecable) will trigger kernel oops. Indeed, if nousb, usb_serial_init will failed, and the usb serial bus type will not be registerd, then usb_serial_register call driver_register which try to register the driver to a not registered bus. Here add usb_disabled() check in usb_serial_register to fix it. Signed-off-by:

Driver originally written by Qualcomm, but rewritten by me due to the totally different coding style. Cleaned up the probe logic to make a bit more sense, this is one wierd device. They could have prevented all of this by just writing sane firmware for the modem. Cc: Tamm Liu <tamml@qualcomm.com> Signed-off-by: -

Currently, the driver only supports PCI and PPC_OF but there are boards like ARM RealView where this is a platform device. The patch adds the necessary functions and registration to the isp1760-if.c file and modifies the corresponding Makefile and Kconfig to be able to use this driver even if PCI and PPC_OF are not enabled.

This patch (as1204) adds a software retry mechanism to ehci-hcd. It gets invoked when the driver encounters transaction errors on an asynchronous endpoint. On many systems, hardware deficiencies cause such errors to occur if one device is unplugged while the host is communicating with another device. With the patch, the failed transactions are retried and generally succeed the second or third time through. This is based on code originally written by Koichiro Saito. Signed-off-by:

commit 64a87b24: [SCSI] Let scsi_cmnd->cmnd use request->cmd buffer changed the scsi_eh_prep_cmnd logic by making it clear the ->cmnd buffer. But the sat to cypress atacb translation supposed the ->cmnd buffer wasn't modified. This patch makes it set the ->cmnd buffer after scsi_eh_prep_cmnd call. The problem and a fix was reported by Matthieu CASTET <castet.matthieu@free.fr> It also removes all the hackery fiddling of scsi_cmnd and scsi_eh_save by requesting from scsi_eh_prep_cmnd to prepare a read into ->sense_buffer, which is much more suitable a buffer for HW transfers, then after the command execution the regs read is copied into regs buffer before actual preparation of sense_buffer. Also fix an alien comment character to my utf-8 editor. Signed-off-by:

A USB-serial converter device is plugged into a system, and a process opens it's device node. If the device is physically removed whilst the process still has its device node open, then other processes can sucessfully open the now non-existent device's node. I would expect that open() on a device that has been physically removed should return ENODEV. This is manifesting itself with getty on my system. I do the following: 1. set up inittab to spawn getty on ttyUSB0, eg: T1:23:respawn:/sbin/getty -L ttyUSB0 115200 vt100 2. Plug in USB-serial converter cable 3. Wait for a login prompt on a terminal program attached to the serial cable 4. Login 5. Pull the USB-serial converter cable from the box 6. getty doesn't realise that ttyUSB0 no longer exists as /dev/ttyUSB0 can still be opened. 7. Re-insert the USB-serial converter cable 8. You should no longer get a login prompt over the serial cable, as the the USB-serial cable now shows up as /dev/ttyUSB1, and getty is trying to talk to /dev/ttyUSB0. The attached patch will cause open("/dev/ttyUSB0", O_RDONLY) to return ENODEV after the USB-serial converter has been pulled. The patch was created against 2.6.28.1. I can supply it against something else if needs be. It is fairly simple, so should be OK. I am using a pl2303 device, although I don't think that makes any difference.

This removes the fallback to the generic method. It is cleaner to explicitely request it. Introducing this was my mistake. This will be solved by an explicit test and the driver being allowed to request what it needs to be done upon resumption. Signed-off-by:

NOP transceiver is used by all the usb transceiver which are mostly autonomous and doesn't require any programming or which are built into the usb ip itself.NOP transceiver only allocates the memory for struct xceiv and calls otg_set_transceiver() so function call to otg_get_transceiver() will return a valid transceiver. NOP transceiver device should be registered by calling usb_nop_xceiv_register() from platform files. Signed-off-by:

This removes an unnecessary check for autoresume from the generic resume method. The check has been obsoleted by the now delayed increase of the usage counter which makes the error this check prevented impossible. This change allows drivers which only use the bulk read URB the use of the generic method even if they support autosuspend. Signed-off-by:
