To accomplish this the function to register a gadget driver takes the bind function as a second argument. To make things clearer rename the function to resemble platform_driver_probe. This fixes many section mismatches like WARNING: drivers/usb/gadget/g_printer.o(.data+0xc): Section mismatch in reference from the variable printer_driver to the function .init.text:printer_bind() The variable printer_driver references the function __init printer_bind() All callers are fixed.

Allow the vbus signal to optionally use polling. This is required if the vbus signal is connected to an non-interrupting io expander for example. If vbus is in polling mode, then it is assumed that the vbus gpio may sleep. Also add an option to have vbus be an active low signal. Both options are set in the platform data for the device.

Fix a potential soft lockup in the AT91 UDC driver by ensuring that the UDC clock is enabled inside the interrupt handler. If the UDC clock is not enabled then the UDC registers cannot be written to and the interrupt cannot be cleared or masked. Note that this patch (and other parts of the existing AT91 UDC driver) is potentially racy for preempt-rt kernels, but is okay for mainline.

Correct hanging while disconnecting the USB device cable. Prevent a race between vbus and UDP interrupts. This bug was tracked on at91sam9260ek boards. A usb resume interrupt was firing after the vbus interrupt : the IP was then already stoped and not able to deal with it (no more clock). A simple interrupt disabling is ok as the "end of bus reset" irq is non maskable and ok to resume the USB device IP.

This patch removes controller driver infrastructure which supported the now-removed usb_ep_{alloc,free}_buffer() calls. As can be seen, many of the implementations of this were broken to various degrees. Many didn't properly return dma-coherent mappings; those which did so were necessarily ugly because of bogosity in the underlying dma_free_coherent() calls ... which on many platforms can't be called from the same contexts (notably in_irq) from which their dma_alloc_coherent() sibling can be called. The main potential downside of removing this is that gadget drivers wouldn't have specific knowledge that the controller drivers have: endpoints that aren't dma-capable don't need any dma mappings at all.

After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).
