[Qemu-devel] [PATCH] vl: Fix compile issue with Werror option

[Mike Qiu]

Currently, if compile with Werror option, the error message shows
below:

  GEN   config-host.h
  GEN   trace/generated-tracers.h
        CHK version_gen.h
  GEN   trace/generated-tracers.c
  CC    vl.o
vl.c: In function ‘get_boot_devices_list’:
vl.c:1257:21: error: ‘bootpath’ may be used uninitialized
        in this function [-Werror=maybe-uninitialized]
         len = strlen(bootpath) + 1;
                     ^
cc1: all warnings being treated as errors
make: *** [vl.o] Error 1

This patch is to solve this issue.
