It is safe. You only have to make certain that the URB is not
deallocated before usb_unlink_urb returns.

This patch adds a function add a group to an existing one and its
counterart. The newly created group behaves as it would be created via
default_groups[] which means the user can't rmdir it.
This should be used by the upcomming USB gadget interface in order to
add the currently available UDCs as a

Hello all,
I have the following situation:
- Device 1 (SAM9G45, Linux kernel 3.2.30 with BusyBox): USB host device
- Device 2 (OMAP4460, Android 4.0.3): USB slave device
These devices are connected through USB1.1 (ohci) interface. I would like
to use the ethernet protocol (CDC ECM) on top of the
pre_eject and post_eject are not used by anyone. Removing them.

Some touchscreens have buggy firmware which claims
remote wakeup to be enabled after a reset. They nevertheless
crash if the feature is cleared by the host.
Add a check for reset resume before checking for
an enabled remote wakeup feature. On compliant
devices the feature must be cleared after a re

Two changes. First we check whenever the request is linked in the work
list and if so take it out. Second check whenever the command is
actually in flight before asking the device to cancel it via task
management, and in case it isn't just zap the data urbs and finish it.

uas_unlink_data_urbs uses this to make sure the the scsi command is
not released while looking at it. This will be needed when we start
calling uas_unlink_data_urbs in the request cancel code paths.
