Subject: Re: [PATCH] usb: dwc2: host: Fix use after free w/ simultaneous irqs

Hi Douglas,

[auto build test WARNING on balbi-usb/next -- if it's inappropriate base, please suggest rules for selecting the more suitable base]

url:    https://github.com/0day-ci/linux/commits/Douglas-Anderson/usb-dwc2-host-Fix-use-after-free-w-simultaneous-irqs/20151015-024824
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)

>> drivers/usb/dwc2/hcd_intr.c:1959:17: sparse: symbol 'dwc2_check_qtd_still_ok' was not declared. Should it be static?

Please review and possibly fold the followup patch.
