Refactor out the code to cache or free endpoint rings from recently dropped or disabled endpoints. This code will be used by a new function to reset a device and disable all endpoints except control endpoint 0.

If we fail to queue an evaluate context command or a configure endpoint command to the command ring in xhci_configure_endpoint(), we need to remove the xhci_command structure from the device's command list before returning. If the command is left on the command list, it will sit there indefinitely, blocking commands submitted after this fails.

This patch (as1316) adds some error checking to usb_submit_urb(). It's conditional on CONFIG_USB_DEBUG, so it won't affect normal users. The new check makes sure that the actual type of the endpoint described by urb->pipe agrees with the type encoded in the pipe value. The USB error code documentation is updated to include the code returned by the new check, and the usbfs SUBMITURB handler is updated to use the correct pipe type when legacy user code tries to submit a bulk transfer to an interrupt endpoint.

On various mxc boards, the intial ULPI reads resulted in a timeout which prevented the transceiver to be identified and thus the ehci device to be probed. Initializing the hardware lines connected to the transceiver (through pdata->init call) before actually enabling clocks and configuring registers in the devices fixes this problem.

Changes: Return an empty string for modulation when there is no connection Fix sysfs unload race conditions Log firmware load process, remove delay Add new configuration interface Remove cxacru-cf.bin Signed-off-by: NSimon Arlott <simon@fire.lp0.eu> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This has never worked properly because wsize passed to cxacru_cm() is incorrectly set to the number of values instead of the data bytes. The maximum number of values that can be set at once is 7 which means the device will not get enough data to work with and none of the configuration values will be used. At least one existing cxacru-cf.bin file contains invalid data which will prevent the modem from syncing properly. Fixing it is likely to break existing systems, and the new sysfs interface for setting configuration parameters can provide the same functionality. A script is provided to convert from the original format. Signed-off-by: NSimon Arlott <simon@fire.lp0.eu> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

The modem can be configured using CM_REQUEST_CARD_DATA_SET, although CM_REQUEST_CARD_DATA_GET does not return any data. Tested by setting the modulation (0x0a) option. There is a list of parameters in the following archive, but the meaning of many of them is not well documented: http://sourceforge.net/project/shownotes.php?release_id=301825 This source also indicates that the highest parameter set is 0x4a but this varies by model so an arbitrary limit of 0x7f has been used (the index is a 32-bit integer).

Firmware writing takes 256ms per 4KB with OHCI, which is very slow compared to 7ms per 4KB with UHCI. Until I have access to a hardware USB analyser it may not be possible to determine why this happens. Instead of appearing to do nothing, log progress when writing firmware and then log the ATM device information when finished. Remove an unnecessary 4 second delay.

It is possible for usb_get_intfdata() to return NULL if sysfs is accessed while the module is being unloaded or the device is being removed. Move the access code to an inline function in usbatm.h, and return -ENODEV if any of the pointers are NULL. It should not be possible for the instance data or atm device to be invalid until after unbind() completes and the sysfs attributes have been removed.

When writing a disc on certain lite-on dvd-writers (also rebadged as optiarc/LG/...) connected to a vt6420, the ATAPI CDB ends up in the datastream and on the disc, causing silent corruption. Delaying between sending the CDB and starting DMA seems to prevent this. I do not know if there are burners that do not suffer from this, but the patch should be safe for those as well. There are many reports of this issue, but AFAICT no solution was found before.

I have a Delkin Devices compact flash card that isn't being recognized using the SATA/PATA drivers. The card is recognized and works with the deprecated ATA drivers. The error I am seeing is: ata1.00: failed to IDENTIFY (device reports invalid type, err_mask=0x0) I tracked it down to ata_id_is_cfa() in include/linux/ata.h. The Delkin card has id[0] set to 0x844a and id[83] set to 0. This isn't what the kernel expects and is probably incorrect. The simplest work-around is to add a check for 0x844a to ata_id_is_cfa().

It's certainly a violation of the ATA specs. Fix it by adding custom ->sff_exec_command method for UDMA33 chipsets.
