linux-next: build warning after merge of the char-misc tree

[Stephen Rothwell]

Hi all,

After merging the char-misc tree, yesterday's linux-next build (i386
defconfig) produced this warning:

In file included from /home/sfr/next/next/arch/x86/entry/vdso/vma.c:25:0:
/home/sfr/next/next/arch/x86/include/asm/mshyperv.h:181:15: warning: return 
type defaults to 'int' [-Wreturn-type]  
 static inline hyperv_cleanup(void) {}
               ^

Introduced by commit

  2e252fbf777d ("x86/hyper-v: include hyperv/ only when CONFIG_HYPERV is set")
