SubjectRe: [PATCH] usb: cdns3: make signed 1 bit bitfields unsigned
Hi Colin,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on usb/usb-testing]
[also build test WARNING on v5.6-rc7 next-20200326]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

url: https://github.com/0day-ci/linux/commits/Colin-King/usb-cdns3-make-signed-1-bit-bitfields-unsigned/20200326-075855
base: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git usb-testing
reproduce:
# apt-get install sparse
# sparse version: v0.6.1-187-gbff9b106-dirty
make ARCH=x86_64 allmodconfig
make C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'

If you fix the issue, kindly add following tag
