Merge tag 'fixes-for-v4.15-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus
Felipe writes: usb: fixes for v4.15-rc4 We have a few fixes on dwc3: - one fix which only happens with some implementations where we need to wait longer for some commands to finish. - Another fix for high-bandwidth isochronous endpoint programming making sure that we send the correct DATA tokens in the correct sequence - A couple PM fixes on dwc3-of-simple The other synopsys controller driver (dwc2) got a fix for FIFO size programming. Other than these, we have a couple Kconfig fixes making sure that dependencies are properly setup.
