usb gadget stack: remove usb_ep_*_buffer(), part 1
Remove usb_ep_{alloc,free}_buffer() calls, for small dma-coherent buffers. This patch just removes the interface and its users; later patches will remove controller driver support. - This interface is invariably not implemented correctly in the controller drivers (e.g. using dma pools, a mechanism which post-dates the interface by several years). - At this point no gadget driver really *needs* to use it. In current kernels, any driver that needs such a mechanism could allocate a dma pool themselves. Removing this interface is thus a simplification and improvement. Note that the gmidi.c driver had a bug in this area; fixed. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
