Subject: Re: [PATCH] uapi: Make generic uapi headers compile standalone.
Hi Jayant,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on linus/master]
[also build test WARNING on v4.17 next-20180607]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
url: https://github.com/0day-ci/linux/commits/Jayant-Chowdhary/uapi-Make-generic-uapi-headers-compile-standalone/20180608-014548
reproduce:
# apt-get install sparse
make ARCH=x86_64 allmodconfig
make C=1 CF=-D__CHECK_ENDIAN__
