Since pre-emption is enabled then it is safe to de-allocate the memory if you first unlink each URB. In this instance you are safe since pre-emption is disabled. If pre-emption and irqs are not disabled then call usb_kill_urb(), else call usb_unlink_urb(). Thanks to Douglas for tracking down this bug originally!!!

2009-01-16pvrusb2: Code module name directly in printkMike Isely
From: Mike Isely <isely@pobox.com> The name of the pvrusb2 module is not likely to ever change, and there are plenty of other places where the name is directly coded, so there is little utility in using a macro to infer the module name here. In addition, using that macro complicates other uses of the driver involving older kernels where this macro works differently. Yes I know for many places we don't have to worry about that. But my alternative is that I have to build special logic in the pvrusb2 standalone driver to special-case what is otherwise costmetic and that is just plain nuts for something as trivial as this, especially since this change does not at all have any compile time or run time impact on the driver. I'm just removing a nicety that didn't have a lot of value here to begin with. Priority: normal Signed-off-by: Mike Isely <isely@pobox.com>
