  "message": "usb gadget stack: remove usb_ep_*_buffer(), part 2\n\nThis patch removes controller driver infrastructure which supported\nthe now-removed usb_ep_{alloc,free}_buffer() calls.\n\nAs can be seen, many of the implementations of this were broken to\nvarious degrees.  Many didn\u0027t properly return dma-coherent mappings;\nthose which did so were necessarily ugly because of bogosity in the\nunderlying dma_free_coherent() calls ... which on many platforms\ncan\u0027t be called from the same contexts (notably in_irq) from which\ntheir dma_alloc_coherent() sibling can be called.\n\nThe main potential downside of removing this is that gadget drivers\nwouldn\u0027t have specific knowledge that the controller drivers have:\nendpoints that aren\u0027t dma-capable don\u0027t need any dma mappings at all.\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n",
