Subject: [PATCH 11/13] kbuild: disable sparse warning "returning void-valued expression"

From: Hannes Eder <hannes@...neseder.net>

The sparse warning -Wreturn-void ("returning void-valued expression")
is off by default, but it is enabled with -Wall, so add
-Wno-return-void to CHECKFLAGS to disable it.
