* usb: otg: twl4030-usb: Fix unbalanced regulator disables at module removalJarkko Nikula2010-12-011-1/+2
| | | | | | | | | | | | | | Function twl4030_usb_remove can cause unbalanced regulator disables in twl4030_phy_power if the cable is not connected. Regulator enable/disable calls are in balance only if the twl4030_phy_resume was called prior the twl4030_usb_remove, that is, the cable was connected. Fix this by checking the 'asleep' variable in twl4030_usb_remove since that variable is used to check state in other functions.

* usb-wwan: implement TIOCGSERIAL and TIOCSSERIAL to avoid blocking close(2)Dan Williams2010-12-013-0/+81
| | | | | | | | | | | Some devices (ex ZTE 2726) simply don't respond at all when data is sent to some of their USB interfaces. The data gets stuck in the TTYs queue and sits there until close(2), which them blocks because closing_wait defaults to 30 seconds (even though the fd is O_NONBLOCK). This is rarely desired. Implement the standard mechanism to adjust closing_wait and let applications handle it how they want to. Signed-off-by: Dan Williams <dcbw@redhat.com>
* USB: Remove unnecessary casts of void ptr returning alloc function return valuesJesper Juhl2010-12-011-1/+1
| | | | | | | | | | | | Hi, The [vk][cmz]alloc(_node) family of functions return void pointers which it's completely unnecessary/pointless to cast to other pointer types since that happens implicitly. This patch removes such casts from drivers/usb/ Signed-off-by: Jesper Juhl <jj@chaosbits.net>
* usbmon: correct length for isochronousPete Zaitcev2010-12-011-3/+31
| | | | | | | | | | | | | | | | | Usually the usbmon returns the amount of data specified in urb->transfer_buffer_length for output submissions and urb->actual_length for input callbacks. However, for Isochronous input transfers, this is not enough, since the returned data buffer may contain "holes". One easy way to fix this is to use urb->transfer_buffer_length, but this often transfers a whole lot of unused data, so we find how much was actually used instead. Original patch by Márton Németh.

* USB: improve uses of usb_mark_last_busyAlan Stern2010-11-163-16/+10
| | | | | | | | | | | | | | | | | | | This patch (as1434) cleans up the uses of usb_mark_last_busy() in usbcore. The function will be called when a device is resumed and whenever a usage count is decremented. A call that was missing from the hub driver is added: A hub is used whenever one of its ports gets suspended (this prevents hubs from suspending immediately after their last child). In addition, the call to disable autosuspend support for new devices by default is moved from usb_detect_quirks() (where it doesn't really belong) into usb_new_device() along with all the other runtime-PM initializations. Finally, an extra pm_runtime_get_noresume() is added to prevent new devices from autosuspending while they are being registered.

* USB: use the runtime-PM autosuspend implementationAlan Stern2010-11-168-167/+71
| | | | | | | | | | | | | This patch (as1428) converts USB over to the new runtime-PM core autosuspend framework. One slightly awkward aspect of the conversion is that USB devices will now have two suspend-delay attributes: the old power/autosuspend file and the new power/autosuspend_delay_ms file. One expresses the delay time in seconds and the other in milliseconds, but otherwise they do the same thing. The old attribute can be deprecated and then removed eventually.

* USB: make usb_mark_last_busy use pm_runtime_mark_last_busyMing Lei2010-11-166-19/+13
| | | | | | | | | | | Since the runtime-PM core already defines a .last_busy field in device.power, this patch uses it to replace the .last_busy field defined in usb_device and uses pm_runtime_mark_last_busy to implement usb_mark_last_busy.

* USB: gadget: file_storage: put_device() in error recoveryMichal Nazarewicz2010-11-111-13/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit fixes some issues with File-backed Storage Gadget error recovery when registering LUN's devices. First of all, when device_register() fails the device still needs to be put. However, because lun_release() decreases fsg->ref reference counter the counter must be incremented beforehand. Second of all, after any of the device_create_file()s fails, device_unregister() is called which in turn (indirectly) calls lun_release() which decrements fsg->ref. So, again, the reference counter must be incremented beforehand. Lastly, if the first or the second device_create_file() succeeds, the files are never removed. To fix it, device_remove_file() needs to be called. This is done by simply marking LUN as registered prior to creating files so that fsg_unbind() can handle removing files.
