Hi,
I've pulled Linus' tree this morning and, after running 'make oldconfig', tried
a build. During that build I got the
following warnings, which look to me like they should be fixed. 'git describe'
shows v5.2-915-g5ad18b2e60b7 and my
compiler is the 20190706 snapshot of gcc 9.

Happy to test any patches, but please cc me as I'm not subscribed to LKML.
