Merge tag 'fixes-for-v3.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus
Felipe writes: usb: fixes for v3.9-rc3 Most fixes are on 'musb' driver. There's a sparse warning fix which marks omap2430_glue as static, a build warning fix which was found with randconfig, a fix for omap_musb_mailbox check and removal of 'select' from musb's Kconfig to prevent Kconfig warnings. Other than that, pxa25x got a fix which was introduced by the latest conversion to udc_start/udc_stop patchset, kernel-doc warnings for composite layer and dwc3 got a build fix on sparc64.
